Continuity mistake: When Memo crashes into the lake the fuel leaks out and the car explodes. Naturally the explosion would have done some massive damage to the car. It then goes to an aerial view of the accident in the next shot and the car is in the same condition it was before it exploded. Then the next scene shows Joe in the garage looking at the wreckage, and the car is blackened and mangled.
Continuity mistake: When Jimmy Bly is in the bar and watches Sophie cross the dance floor, she is wearing a white top that is very low cut and open, showing lots of skin. But, as he talks to her at the bar, she is wearing a black top that covers way too much at the neck, for it to have been under the very low cut white top she was wearing earlier, that she is now holding in her hand. The black top would have been visible, had she really worn it underneath the white top.
Continuity mistake: In the final race you see the Pioneer Worldcom car get hit 3 times in 2 crashes (it was totaled twice). Not only do they use it after the first crash, you see it in the pits when they make the final pit stop. Pioneer Worldcom only has ONE car in the field. The helmet of the driver didn't even change.
Continuity mistake: When Memo has his wreck, it is absolutely ridiculous to think that it would take the rescue team that long to get to the accident. Joe runs all the way from the pit paddock and arrives at the same time as the rescue workers. Furthermore, the methanol fuel is contained in a fuel cell which would not leak as the movie shows. It is impossible for a methanol fueled car to explode like that.
Continuity mistake: When the two drivers jump into the prototypes, they don't put on their seatbelts (which are 5 point straps). When racing through the streets you can see that they both have their seatbelts on. Going 200 mph through the streets of Chicago, you would not have the time or the control to fasten a 5 point seatbelt.
Continuity mistake: When "The Vistion Car" spins going into turn 3 at Toronto on the first lap it shows him sliding sideways into the black tyre barrier which has a large cement wall behind it. The next shot is him going nose first into a red-and-white tyre barrier with a nice big gravel run-off area behind the tires. No more concrete. When he hits the tires there is a small fireball, which would never happen if a CART car were to hit head on like that. (00:33:58)
Continuity mistake: When Slyvestor Stallone is driving in the car to prove himself to the team, he does the 3 coin trick. When he runs over 2 of the 3 coins, you can see them fly up into the air, however, when they check over the tyres at the end, all 3 coins are in the tire.
Continuity mistake: In the German race, you see Memo getting ready to pass Jimmy. In this moment the Motorola car is piloted by Beau. You can see the Target visor. (01:14:35)
Continuity mistake: Memo Moreno overtakes Michael Andretti. The car he is shown passing is the Visteon of Roberto Moreno at first, and the switches to the Newman Haas of Andretti. (01:14:00)
