Tiny cars freak the hell out of me. I would be terrified driving any of these in traffic. It would be like rolling around in cardboard and would provide less protection.
They have a place in my town where they have set up tiny buildings and have cars that the kids can drive to learn the rules of the road and help their parents by teaching them not to text or talk on the phone while on the road. Those little cars go very slow but I am always afraid of hitting the kids who are learning how to cross the streets. Everything is enclosed but there are just too many distractions.
For this reason I need to be in something huge - or at least bigger than I am so that when I hit something, I will survive the impact. I so totally know what to do to keep the bus under 50 mph when the bomb is strapped under it.
