Fit,fast, riders always seem to be anti bike lanes. Slower rider usually like bike lanes.They know they don't want to drag along at 12 mph holding back angry drivers, so a lane is just fine for them.If you can sustain 25 mph, sure take a lane, you aren't really holding back most city drivers.
This is one of those elite vs the rest of us issues.The rest of us rarely frequent bike forums of course, so any survey here wouldn't really tell us much.
