I'm curious about this too. In SF it can make sense to have a car even just for travel within the city because public transit to/from certain areas can take forever compared to cars. I was just dragging points around between random places on Manhattan and Brooklyn, and the difference in transit times between cars and public transit seemed pretty minimal almost everywhere I dragged the points to. In SF, there are certain well served areas where that is also the case.. but if you want to cut west from, say, Dogpatch to the Castro, it can take 2x-4x longer by public transit.
