I think these tiny cars would be fine for trips around the neighborhood and to the store, but not distance or highway use. My fear is that once a few families in these tiny cars have a disagreement with a semi or dump truck and the worst happens, people will take a second look and compare safety with saving gas (ie the pinto bomb). Way to many factors up in the air so far to make any 100% conclusions, but for me, i'll stick with 17 mpg and have some room to stretch out and be comfy, jmho, bob
