Opinion for the Court filed by Circuit Judge WALD.
Appellants Antoine D. Washington and Glen Early were each convicted after a jury trial of one count of possession with intent to distribute cocaine, in violation of 21 U.S.C. § 841(a)(1) (1988) and 18 U.S.C. § 2 (1988). Together, Washington and Early raise eight challenges to their convictions. Because we disagree with each of the defendants’ arguments, we affirm. We reject the assertion that the trial judge erred in denying Early’s and Washington’s motions to suppress evidence, Washington’s motion to sever the trials, and Early’s motion to suppress photo identification testimony. We also find that the district court properly admitted “other crimes” evidence about Early and we disagree with the defendants’ claims that there was insufficient evidence supporting their convictions of aiding or abetting the possession of cocaine. Nor are we persuaded that reversal of Early’s conviction is warranted by the district court’s decision to deny Early’s motion to introduce only the impeaching portions of prior statements by government witnesses. Although the jury instructions contained an unconstitutional reasonable doubt instruction, the district court did not commit plain error, and this is not a ease in which the supervening-decision doctrine counsels reversal. Finally, we hold that the district court did not err in enhancing Early’s sentence for reckless endangerment of the public.
I. BACKGROUND
On February 18, 1992, the District of Columbia Metropolitan Police Department broadcast a lookout for a man with a gun in the vicinity of a McDonald’s restaurant at Peabody Street and Georgia Avenue, N.W. In connection with that broadcast, a further lookout was announced for three black men in a burgundy .four-door car. Officer Hemp-hill, who was in the lookout area, spotted three black men in a red two-door Mazda. Early was the driver, Washington was in the front passenger seat, and Daniel Wright was in the back seat. 1 After Hemphill, who was driving in a marked police car, activated his siren and ordered the Mazda to stop, the driver obeyed. As Hemphill approached the car on foot, Wright told Early to “pull off’ because he had drugs in his possession, and the Mazda sped away. Hemphill then returned to his car to broadcast a lookout, which was heard by Officers Jewell and Iuz-zolino, who were in a patrol car coming from the opposite direction of the Mazda. When Jewell and Iuzzolino saw the Mazda, they chased it into an alley. The Mazda slowed, and Washington’s seat moved forward as Wright jumped out of the passenger side door, carrying a clear ziplock bag containing a white or light-colored substance. Wright then crossed in back of the car to the driver’s side. After running quickly in tandem with the Mazda for about one block, Wright threw the plastic bag into the car through the driver’s side window. He then split away from the Mazda and Iuzzolino pursued him on foot.
Soon thereafter, Early lost control of the Mazda and it flipped onto the driver’s side. Earlyand Washington climbed through the passenger’s side window and fled from the car. While running, Early held his left arm as if it was injured. Officer Jewell radioed for assistance and then went to the spot where Washington had scaled a fence. There she found a Bell Atlantic pager which had been purchased by Early. Meanwhile, in response to Jewell’s broadcast, Officer Le-sher spotted Washington emerging from an alley. Lesher chased Washington and apprehended him within a block of the Mazda. Washington had $586 in cash and a pager on his person. Iuzzolino and Jewell returned to the Mazda and saw, lying inside the over *1132 turned car. on top of the driver’s side door, a plastic ziploek bag containing white rock chunks in plain view. The .bag was seized without a warrant and was found to contain narcotics.
Later, Officer Brigindi investigated the Mazda’s license plate number and discovered that the car was registered to Glen Early. About a week after the car chase, he obtained a single photo of Early and showed it to Iuzzolino, who recognized Early as someone he had seen before on his beat and as the driver of the Mazda.. Brigindi obtained an arrest warrant for Early and took him into custody. At the time of the arrest, Early was wearing a east on his left arm. On Early’s person was a beeper, some money, and personal papers, including a Kaiser Per-manente health card in the name of Marcus Williams, who is Early’s cousin. The record shows that the day after the car chase, someone used this health card to receive treatment for an injury to his left arm, and that person was not Marcus Williams.
On July 14, 1992, Judge Harris issued a memorandum opinion in which he denied: (1) both Washington’s and Early’s motions to sever; (2) Early’s motion to suppress the plastic bag containing drugs; and (3) Early’s motion to suppress identification testimony based on the showing of a single photograph. Memorandum Opinion, July 14, 1992 (“Mem. Op.”). The district court reserved judgment on Washington’s motion to suppress the tangible evidence recovered from his person at the time of his arrest. At the suppression hearing on July 15,1992, Judge Harris orally denied Washington’s motion to suppress the evidence recovered from his person. On the second day of trial, Early renewed his motion to suppress the drugs found in the car. The district court denied the renewed motion.
On July 21, 1992, Washington and Early were each convicted by the jury on the possession count. Washington was sentenced to 151 months in prison and Early was sentenced to 174 months in prison. In total, Early and Washington raise eight challenges to their convictions, each of which we will address in turn.
II. ANALYSIS
A. Unreasonable Search and Seizure
Early challenges the district court’s denial of his motion to suppress the evidence retrieved from the Mazda. Early contends that when Officer Hemphill activated his sirens and ordered the driver of the Mazda to stop, he effectuated a seizure within the meaning of the Fourth Amendment. It is well-established that “‘a person has been “seized” within the meaning of the Fourth Amendment only if, in view of all the circumstances surrounding the incident, a reasonable person would have believed that he was not free to leave.’ ”
United States v. Jordan,
The district court found that the warrantless seizure of the drugs from the Mazda did not violate the Fourth Amendment because the vehicle was abandoned once the defendants left it overturned in the alley and fled the scene, and the plastic bag which appeared to contain drugs was in plain view inside the overturned Mazda lying on top of the driver’s side door.
See generally United States v. Thomas,
Washington also contests the district court’s denial of his motion to suppress the money and pager seized from his person by Officer Lesher. Washington claims that the physical evidence seized from his person is the fruit of a poisonous tree — the initial stop of the Mazda. As discussed previously, however, there is no poisonous tree; Hemphill’s stop of the Mazda was not a seizure in violation of the Fourth Amendment. More important, the totality of the circumstances reveals that by the time Washington was searched, there was probable cause for his arrest.
See Illinois v. Gates,
B. Motion for Severance
Before trial, Washington moved for severance, claiming that Early would present exculpatory testimony to the effect that Washington lacked knowledge of the drugs seized from the car. The district court denied the motion. On appeal, Washington challenges the district court’s refusal to sever his trial from that of Early. Under Rule 14 of the Federal Rules of Criminal Procedure, a district court may grant a severance “[i]f it appears that a defendant ... is prejudiced by a joinder of ... defendants.” Fed. R.CRIM.P. 14 (1993). Due to the permissive language of Rule 14, we accord great deference to a district court’s decision to deny severance.
See United States v. Harrison,
In
United States v. Ford,
When fulfilling the
Ford
conditions, the movant must demonstrate the substance of her co-defendant’s testimony with specificity sufficient to show that the testimony will be “substantially exculpatory.”
See Harrison,
C. Suppression of Photo Identification Testimony
Early next contends that the district court erred in refusing to suppress all testimony relating to his out-of-court and in-court identifications. Early asserts that the use of a single photograph to identify him as the driver of the Mazda was unnecessarily suggestive and conducive to an irreparable mistaken identification and therefore violated his due process rights. Based on the tag number of the Mazda, Officer Brigindi obtained a photograph of the person to whom the car was registered — Glen Early. Approximately seven ■ days after the car chase, Brigindi showed that single photograph to Officer Iuzzolino, who identified the person in the photograph as the driver of the Mazda. Brigindi testified that Iuzzolino knew the photo he was viewing related to the February 18, 1992, incident and that Iuzzolino recognized Early from the neighborhood. Subsequent to Iuzzolino’s identification, Early was arrested. At the police station, Brigindi showed the same photograph to Officer Jewell and she too identified Early as the driver of the Mazda.
Our decision is controlled by the two-step inquiry compelled by the Supreme Court in
Neil v. Biggers,
the opportunity of the witness to view the criminal at the time of the crime, the witness’ degree of attention, the accuracy of his prior description of the criminal, the level of certainty demonstrated at the confrontation, and the time between the crime and the confrontation.

D. Admission of Rule b0h(b) Evidence Against Early
Washington contests the district court’s decision to admit testimony that Early used a false identity to obtain medical
*1135
treatment the day after the ear chase, arguing that the testimony constituted “other crimes” evidence prohibited by Federal Rule of Evidence 404(b).
2
Rule 404(b) prohibits the admission of evidence of a person’s other crimes if such evidence is used to demonstrate that person’s character.
See
Fed. R.Evid. 404(b) (1993). Nevertheless, Rule 404(b) bars only the introduction of evidence offered
solely
to show a defendant’s character, and the testimony pertaining to the use of the Kaiser Permanente health card was offered for a different and proper purpose of proving Early’s identity as the driver of the ear.
See
Fed.R.Evid. 404(b) (evidence of other crimes may be admissible to prove identity);
see also United States v. Washington,
Washington also argues that the district court erred by failing to conduct an on-the-record balancing of the probative value of the testimony against its prejudicial effect.
See
Fed.R.CRIM.P. 403 (1993) (“evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice”). While this balancing should ordinarily occur on the record, we will not automatically reverse or remand for failure to do so if defense counsel failed to request such a balancing, or if “the considerations germane to balancing probative value versus prejudicial effect are readily apparent from the record.”
United States v. Manner,
E. Sufficiency of the Evidence
Both Early and Washington allege that the government failed to introduce sufficient evidence to convict them of possession with intent to distribute cocaine in violation of 21 U.S.C. § 841(a)(1) and 18 U.S.C. § 2(a). Under 18 U.S.C. § 2(a), a person who “aids, abets, counsels, commands, induces or procures” a crime is punishable as a principal for that offense. As we have repeatedly indicated, a defendant faces a high threshold when seeking to overturn a guilty verdict on the grounds of insufficiency of the evidence. Our review is confined to the question “whether, after viewing the evidence in the light most favorable to the prosecution,
any
rational trier of fact could have found the
*1136
essential elements of the crime beyond a reasonable doubt.”
Jackson v. Virginia,
Early arid Washington both contend that there was insufficient evidence to establish that they actually or even constructively possessed the cocaine. Instead of demonstrating actual or constructive possession, however, the government only needed to prove that the defendants aided or abetted Wright’s possession of the drugs.
See United States v. Poston,
“(1) the specific intent to facilitate the commission of a crime by another; (2) guilty knowledge on the part of the accused; (3) that an offense was being committed by someone; and (4) that the accused assisted or participated in the commission of the offense.”
United States v. Harris, 959
F.2d 246, 262 (D.C.Cir.) (quoting
United States v. Raper,
1. Early’s Conviction
In this case, a reasonable juror could have found.that Early was attempting to assist Wright by evading the police after the initial stop of the Mazda. At that point, Early knew that Wright possessed drugs. Early interrupted a high speed chase to allow Wright to get out of the car. After jumping out of the car on the passenger’s side, Wright crossed over to the driver’s side and ran alongside for a little less than a block. A reasonable juror could have concluded that Wright and Early were trying to determine a course of action and that they decided the drugs would be safer in the car. In addition, when the police arrested Early several weeks after the car chase, he had a pager and $592 in cash on his person. From this evidence, a reasonable juror could have decided that Early aided or abetted the possession of cocaine by trying to prevent the police from seizing the contraband.
See United States v. Poston,
2. Washington’s Conviction
The sufficiency of the evidence to convict Washington of aiding or abetting the possession of the drugs is less cut-and-dried. There is no evidence that Washington knew of the existence of the drugs until Officer Hemphill ordered the Mazda to stop. According to Washington’s testimony, at that point, Wright told Early to “pull off’ because he had drugs on him. Early “pulled off’ before Washington had time to exit the car. Although his seat had to be moved forward to allow Wright to leave the car, Washington testified that he did not voluntarily help Wright. Nor can Washington be convicted of aiding or abetting Wright merely because he failed to jump out of the Mazda when it slowed to let Wright out. “[I]t is not a crime simply to travel — even knowingly — with someone who is carrying drugs; to be liable for the substantive offense, one must actively seek to aid or assist the person in possessing the drugs.”
United States v. Teffera,
Nonetheless, in a single sentence of testimony at trial, Washington diminished substantially his chance of succeeding on an insufficiency of the evidence claim. On direct examination, when asked why he ran after the Mazda overturned, Washington explained: “I was scared ... because the police ... [would] try to lock me up ... because I pulled the package through the window.” Pulling the bag of drugs through the window clearly qualifies as aiding or abetting. In addition, when the police caught Washington, they found on his person a beeper purchased by Early and $586, which included nine ten-dollar bills, thirteen twenty-dollar bills and four fifty-dollar bills. The narcotics expert testified that one would expect to find bills of such denominations on a drug dealer, and that drug dealers often provide beepers to their assistants.' Therefore, taken as a whole, this evidence is sufficient for a reasonable juror to conclude that Washington aided or abetted the possession of the cocaine.
F. Rule of Completeness
At trial, Early pointed out three inconsistencies between the trial testimony of Officer Iuzzolino and his prior statement made on the day of the ear chase. Early also fleshed out a discrepancy between- Officer Brigindi’s testimony at a preliminary hearing on March 11, 1992, and information provided by Early on a police form on the evening of his arrest. At the close of his ease, Early sought to introduce only the portions of the officers’ prior statements that contained the impeaching information. The district court responded that it could not admit selected portions of the prior statements, and the government agreed, claiming that the prior statements should be admitted in their entirety, or not at- all. Early again attempted to introduce only the impeaching portions of the prior statements. The district court refused, and Early responded “Okay.” Relying on our opinion in
United States v. Rogers,
The district court based its decision to exclude the portions of the officers’ prior statements which contained impeaching material on the rule of completeness. Under the rule of completeness, which is contained in Federal Rule of Evidence 106,
3
“where substantial parts of a prior statement are used in cross-examination of a witness, fairness dictates that the balance be received so that the jury will not be misled.”
United States v. Rubin,
G. “Strong Belief’ Jury Instruction
On appeal, both defendants challenge the constitutionality of the jury instruction. At trial, the district judge instructed the jurors that they could find guilt beyond a reasonable doubt if the evidence caused them to have a “strong belief’ in the defendants’ guilt. We have recently held that a jury instruction which equates “beyond a reasonable doubt” with “strong belief’ is constitutionally deficient.
See United States v. Merlos,
The plain error standard requires us to determine: (1) whether there is unwaived legal error, (2) whether the error was “plain” or “obvious” under current law, and (3) whether the error was prejudicial.
United States v. Olano,
Our analysis does not end there, however. In the interests of justice; “we are bound to consider any change, either in fact or in law, which has supervened since the [trial court’s] judgment was entered.”
Patterson v. Alabama,
In this case, however, the supervening-decision doctrine does not apply to provide relief to the defendants. At the time of trial, the constitutionality of the “strong belief’ jury instruction was not so well-established that any objection would have seemed futile. No court of appeals had upheld a jury instruction which equated “strong belief’ with “beyond a reasonable doubt.” In addition, the defendants had been put on notice that a plausible objection to a reasonable doubt instruction might have an especial advantage because of our previous insistence that “[a]n instruction central to the determination of guilt or innocence may be fatally tainted by even a minor variation which tends to create ambiguity.”
United States v. Rhone,
H. Reckless Endangerment
Early’s final claim is that the district court erred in enhancing his offense level under section 3C1.2 of the Sentencing Guidelines.
See
U.S'.S.G. § 3C1.2 (increase by 2 levels if defendant “recklessly created a substantial risk of death or serious bodily injury to another person in the course of fleeing from a law enforcement officer”). We review the district court’s decision for clear error.
Cf. United States v. Thompson,
III. Conolusion
For the foregoing reasons, we affirm the convictions of Early and Washington. We reject the defendants’ challenges .to the district court’s denial of the motions to suppress evidence, to sever their trials, to suppress photo identification testimony, to admit “other crimes” evidence about Early, and to the *1140 trial court’s refusal to introduce the impeaching portions' of prior statements by government witnesses. In addition, we find that a reasonable juror could have found sufficient evidence to convict the defendants of aiding or abetting the possession count. While the jury instruction contained a constitutionally deficient reasonable doubt instruction, the instruction was not plainly erroneous. Nor was the apparent constitutionality of the instruction so well-established at the time of trial as to. render objection futile. Finally, we hold that the district court properly enhanced Early’s sentence for reckless endangerment of the public.
Affirmed.
Notes
. We note that it is not clear that Washington has standing to raise the Rule 404(b) argument on appeal.
See United States v. David,
. Rule 106 states in full: "When a writing or recorded statement or part thereof is introduced by a party, an adverse party may require the introduction at that time of any other part or any other writing or recorded statement which ought in fairness to be considered contemporaneously with it.’ Fed.R.Evid. 106.
. Officer Iuzzolino was impeached for the following three inconsistencies: (1) the police report he prepared on the day of the car chase stated that the Mazda “slowed down” but at trial he stated that it “stopped"; (2) the report stated that Wright was carrying the plastic bag in his left hand but at trial he stated that Wright carried the bag in both hands; and (3) the report stated that Wright threw the drugs in the car but at trial he claimed that Wright "handed-off” the drugs into the car. Officer Brigindi was impeached for stating at a preliminary hearing that Early never gave his proper name during the evening of his arrest when Early actually wrote his name down on one of the police forms. Id. at 180.
