I think we're in on the ground floor of something here! There are whole new industries to be created after this great discovery by scientists: Really little seat belts and air-bags (rats don't seem to be very good drivers, worse even than many drivers in New Mexico!), miniature cup holders, and other automotive accessories, a whole new legal system--rats suing rats over minor fender benders, hiring rat lawyers, etc. etc.
I want to form a start-up making teardrops, and other RV's for rats, that they can tow behind their miniature cars. We could call them "rat's nests". Hmm, okay, I'll come up with the ideas, and someone else can name them...
