One thing I hate about racing games...

I just downloaded the demo of dirt and its not bad but not as fun as I would have thought. anyway I was driving the citroen c4 around the italy track and I like cutting things fine so I drive quite close to walls to cut times but it pisses me off when the car suddenly stops with shards of glass flying everywhere and massive damage to the front end but no physical object that could have created it. I reviewed the replay footage and there was plenty of room to move. I did take some pics but they wont show up on here. some error about the word "class"??? no idea. anyway I think I am going to rent Dirt first....
