I just tried out the car and thought it was awesome. As mentioned previously, it has some strange handling issues. When you are going really fast and then turn, it seems like you are more sliding on ice than turning on pavement. It tends to slide you sideways. Maybe you meant to do that though for the sake of realism. Maybe it would help to add some friction effects (have the car shake slightly when you stop or when you make sharp turns). That would probably add a great deal of realism.
The model is sweet BTW! I especially liked the wheels.
I found this bug.
I rammed into the wall and the car drove up it. When it landed, it landed like this. When I turned, it turned the car on the Z axis still even though the car was vertical. I couldn't get it back down after that.
This is an excellent project. I am very impressed. Keep up the good work.
If curiosity killed the cat then perhaps Curious George killed the cat.
But Cat's do have nine lives so who knows?
