I bet they're more like 4 wheelers or golf carts to rats than cars. I think they're simply just having fun. Or maybe it's similar to the whole pavlov's dog thing, drive a car and get a treat. Eventually driving is associated with treats. Now it would be interesting to see them making the rats drive to something stressful like us having to go to work has an effect on stress. Then maybe developing a Rat uber to see if riding in a rat car to a treat will have a net gain or loss on stress....okay I just wanted an excuse to mention rat uber in that last sentence.
