The problem is, dooring only affects the doorer after it happens. Most other traffic violations, like speeding, blowing stop signs, failure to yield, etc, can get you a ticket regardless of their outcome. Opening a car door into traffic, in Chicago at least, puts you at fault but there's no getting a ticket for not looking. There's only a ticket after your action causes an injury. Obviously, we can't have police ticketing everyone parallel parking for not looking in their mirror, so we think we need to attack this from an education perspective alone. I propose instead, we stop trying to segregate bikes into lanes that they don't fit into! Good bike lanes have a buffer between cars that makes dooring almost impossible. Bad: |B|C Good: |B|\|C Where B = Bike and C = car and slashes and pipes = paint on the roads.
