power wheels

I was in Soho on a Friday evening in March to try out a mexican, hipster street vendor based on a friend's recommendation. I never found the truck but happened to chance upon a street vendor trying to transport his cart at rush hour. Most street carts have power-driven motors. However, this guy gets caught in traffic and eventually moves onto the sidewalk, even though I learned from Alex that carts are not to be driven on the sidewalk. Difficult!
