A witness said he stepped outside when he saw eight people with hoodies on walk up to one of the cars.
"I thought they looked like they were up to no good and then sure enough they walk up to this Smart Car right here, all huddle around it and just lift it up and set it on its hind legs, like a dog on its hind legs, -- that's pretty much it," said witness Brandon Michael.
San Francisco police are treating the case as felony vandalism and have not made any arrests.
