The damage is set too low. I mean there are armour upgrades if you don't want to bash you're car. Most people don't give a f*ck but to me it's a big thing. With increased sensitivity gta could have had damage like next car game or slightly lesser with lesser parts falling off. The stupid explosions are beyond annoying. I wanted to see the crumpled mess of my car after rolling down chilliad, but no the car has to explode after hitting it's roof hard as if it has a gas tank on it's roof.
GTA IV is the closest thing to Next Car Game, and it was on 360/PS3! While the damage is excellent in IV, all it needed was car parts falling off other than the doors/the hood.
