Corrected entry: When Iron Monger throws Iron Man into the bus and it explodes, an Audi R8 suddenly appears on the road. This is explained in the deleted scenes, where Rhodes drives an Audi R8 into Iron Monger to help Tony, but still a mistake in the finshed movie.

Correction: Though explained in deleted scenes this could also be seen to the audience as just someone else with the car in the wrong spot at the wrong time.
