Make parking in bike lanes illegal by dafault, and enforce it.
A bike lane that allows parking is a parking spot, not a bike lane. Cars parked in a bike lane force the bikes into the traffic lane, utterly negating the point of the bike lane in the first place.
If on street parking is required, have parking on one side of the street, and two-way bike lanes on the other.
The danger in forcing bikes into lanes may not apply so much to hard-core road bikers and expert commuters, but more to the extra vulnerable: kids, families with baby carriers, or any more timid biker group.
