trouble is, when you piss off the drivers, they vote you out.
Vancouver is pretty bike friendly and the goal is to get bike use up to 10% of all travel, but one big issue is to take away a lane used by drivers on a major bridge for use by cyclists but the last time that went through a trial (the council actually took 2 lanes away from drivers) all council members and mayor that supported the temporary trial lost the seats in the next election.
