So I'm confused about two things:
1) I've recently discovered a load of videos on Youtube of cars flying hundreds of feet up in the air, tumbling down the road in spectacular fashion. Was this a glitch that has since been patched? In my many, many hours in GT5 I've never come across anything close to this behaviour?
2) Also, has the cosmetic damage been toned down since launch? I remember on launch day, people were posting pics of massively deformed cars, headlights on top of bonnets and that kind of thing, but again, I've never seen anything like that.
