That so doesn't work in the real world, though.  Residential streets are
typically about 35 feet wide curb to curb.  Is this lanes=4 or lanes=2?
Trick question, it's neither because parking is allowed on the curb on both
sides and the middle portion isn't wide enough to allow to cars to pass
side to side in the middle.
