Here's one I see people frequently refusing to comply with:
21717. Whenever it is necessary for the driver of a motor vehicle
to cross a bicycle lane that is adjacent to his lane of travel to
make a turn, the driver shall drive the motor vehicle into the
bicycle lane prior to making the turn and shall make the turn
pursuant to Section 22100.
Recently I've actually seen people REFUSING to merge into a bike lane to turn right to the right of thru traffic. What's the problem here? What can we do to make people understand it's ok (and actually a good idea) to drive your car in the bike lane if you're making a right turn (so cyclists in the bike lane don't try to pass right turning cars on the right)?
