To make matters worse for Jump on the Jam, there's two or three vehicles BEHIND the parking garage, in the tiny gap between the structure and the large ramp from Return of the Semi. It's only possible to get to them in the PS2 / Xbox releases by getting the slowest possible start. Those same cars also sit there in Return of the Semi. Earlier versions of Revenge allow for more physics tomfoolery, which let me hit the buses at Smackeroni and still make it all the way down. By extension, I managed to get all 84 cars in Drain Damage, perhaps the largest junction where this is possible.
