Tell everyone you're a tourist by renting a Go-Car in San Francisco and site-see away. Hey, I kid… it's a good idea. This story is thanks to our sister-site Gadling.com, the engaged travel blog. These little yellow three-wheeled cars are GPS guided and gives you a tour of the San Francisco area. Top speed is 35 miles an hour. Look kids, Haight Ashbury, Golden Gate! Smile and say "nerd"!
