In the US I had a Neighborhood Electric vehicle called a Kurrent. It was great but I'm pretty sure Smart Cars are not electric. Unless they have just come out with one in the past few months.
I own a Smart Car (Passion) here in CO. You're correct though, it is gas only. We get 46 mpg in the city here and love it but, have been told by customs we can't bring it. My husband feels it wouldn't do well on the roads in AC, too low on the clearance.
The reason I like it over an electric car is my friends who are firemen have issues with the electric cars and getting people out of them once they are in a crash and people are hard to get out of them.
