This is weird... On the New York map, there's a museum or something at the west end of the map. You can drive up a ramp to get to it, and drive around it and come back down the ramp--the road around it is only about a lane wide. Here's the weird part... There's a low wall along the street by the entrance. Go to the NORTH end of that wall, and drive onto the sidewalk and into that corner where the wall meets the building. The car suddenly jumps into the air, and floats along in the air next to the building for a while, then falls to the ground and flips over. After several tries, I got it to land upright and drive around a little, but it soon jumped in the air again for no apparent reason and flipped again. Is this a bug, or are you supposed to be able to jump the wall and drive around in that lot? (I haven't gotten that far in the Undercover missions, so I don't know if it figures into one of the missions...)
