@4: You are wrong. SMC 11.58.050:
"No person shall enter, leave, or open the door of a motor vehicle on the
side adjacent to moving traffic unless and until it is reasonably safe to do
so, and can be done without interfering with the movement of other traffic,
nor shall any person leave a door open on the side of a vehicle adjacent to
moving traffic for a period of time longer than necessary to load or unload
passengers. (RCW 46.61.620)"
