4) Turning Circles

I can't really explain it properly but in my mind these cars will have the bigger turning cicles in order:

AWD/4WD
RWD
FWD

Because in FWD the power and steering is one, therefore when you try to steer both are applied at the same time. With RWD, you have the steering the power at opposite ends, so basically you require space to put out the power. In AWD, the power is divided by even more space.

Meh, I'm not thinking.
