There is a masochistic bicycle event every year when a group of bikers rides to, and up, a dozen of the steepest hills in town. Maybe it's 13.

The camera angle is slightly tilted. That is a contender for steepest residential street. San Francisco has many contenders. Any mountain state probably has many steeper roads. I drove on some.
