ExtremeNinja I've done some extensive
testing crashing and here are my conclusions. I have a Logitech Driving Force GT on the PS3.
Firstly in Vehicle mode the pedals are non-responsive in both control settings, depending on the settings to accelerate you can either use X or R2 on the wheel. R2 is quite hard to use as a main button as it's on the shoulder of the wheel.
The steering does work but very unresponsive, In GTA you need to be able to make rapid changes of direction, these aren't possible using the wheel, it's like driving a barge, you have to plan your turn well in advance, no handbrakes, doughnuts or pedestrian mowing.
You don't have the same thumb controls which also makes shooting from within a vehicle impossible unless they are straight in front of you.
On foot it is an impossible task, you can turn left or right but you are unable to walk forward or backwards, I had to kind of stagger towards a car to try and get in it. Forget trying to do anything else with it!
It's not a game designed to be used with a wheel and I don't think they will be adding the support for V either.
