Small compact cars have only started to become popular in North America fairly recently, so the selection we have here is quite limited in comparison to Europe. This is why we aren't seeing vehicles like this Peugeot bubble car concept designed by Yuji Fujimura for the European auto maker.

While the Peugeot bubble car does remind me a little bit of that movie Bubble Boy, this futuristic pod-like vehicle would still be great for riding around the city.
