I don't know where Henry Street in Madison is... but due to the nature of the dooring I assumed it was in a commercial area. (yeah, I made an assumption)

In my older residential neighborhood, every one goes down the center of the street, the streets are simply too narrow otherwise. I therefore guessed that Henry was a commercial street with traffic that passed on either side of a center double yellow with parked cars on either side... such street configurations are common in America... and there is usually about 3 feet or so between moving cars (not delivery trucks, as you point out) and parked cars and about 3 or more feet between vehicles on either side of the center.






If a door extended 38 inches and you were 48 inches out I think you might hit said door by 2 inches... assuming a 24 inch hand to hand distance.

So should we lobby Madison for a cyclist 48 inch rule instead?
