Smart cars are so adorable you just want to pick them up and put them in your pocket. Whenever I see one, I hope these extremely efficient and small-is-beautiful Mercedes are counterbalancing the horrendous number of gas-guzzling black SUV's picking up in the city. The jelly bean-sized cars are so well-designed for the Rush Hour maze that even the NYPD bought a fleet.

Some owners can't resist gloating. When I saw this blue subcompact backing up into a luggage-sized space, I thought, what a real New York car.  It wasn't just Smart, it was also Smart-ass.
