Intersections of car lanes and bike lines should also be designed in such a fashion that the lanes meet mostly at a right angle. Sharp turns and buffer spaces. A sharp turn slows the car traffic and the right angle at the intersecting point makes it easy to check for crossing (cycle) traffic. See for example this video http://www.youtube.com/watch?v=FlApbxLz6pA
for example, i do a lot more shoulder checks to the right. i'm a very fast cyclist and sometimes overtake drivers on the right (when riding in the bike lane). some drivers can't fathom a cyclist being faster than them.
the other thing is mirror checks when opening the car door. i even started to reprimand other drivers or passengers (depending on my role) for not checking. even though i'm riding fast i'm trying to be safety conscious and always assume a driver in a dangerous spot hasn't seen me; this is impossible for suddenly opening car doors.
What I'll do is move further to the right when preparing to make a right turn in order to prevent cyclists from passing on the right. As a cyclist, I won't pass other vehicles on the right if there's a possibility that they could make a right turn, or a car from the opposite direction could make a left through a gap of stopped traffic, or a car approaching on the intersecting road on my right may not see me before pulling out.

You can avoid opening car doors by riding at least 6 feet away from parked cars. I ignore door zine bike lanes and just ride in the center of the rightmost general purpose lane. Faster traffic can change lanes to pass me.
The problem is that the vast majority of motorists do not have significant experience riding a bicycle, so they don't know where to look for cyclists and will end up colliding with them when they pop out from behind parked cars within 30 feet of the intersection (when traveling at 20 feet per second).
