I always think of Vigilante 8 - Second Offense on the Dreamcast. I would be driving down a road and I'd just fall through the polygon road partially, and the game would try and push be back out, but it'd leave me vulnerable as I'm partially sticking out of the road. One time I nearly fell through the ground, and the game realized it and rubber banded my car, shooting it into the sky so high I couldn't see the ground anymore, being airborne for a good twenty to thirty seconds. Speaking of airborne, the flight pods that you could pick up in the game must have not been playtested too well because they barely worked in comparison to older versions. Despite the horrible glitches, I still did love that game , car combat games are my favorite genre.
