Those "lanes" decrease safety. We have plenty of them here because it's just paint so it costs nothing. Just look at the picture on the linked site. Left of the dotted line is where I would be just to keep enough space to opening car doors. But now there is a dotted line and lots of bicycle symbol paint in it so I get all the nutjobs driving at me to tell me I should ride in that "bicycle lane". And beginner cyclists who do end up riding in that lane get a double whammy, car doors in their face and cars passing way too close because they think the dotted line somehow means you don't need to keep space when overtaking. Notice that cyclists in those lanes have priority over turning vehicles! You have to be suicidal to get anywhere close in one of them to a vehicle that has "mysteriously slowed" (no signal of course) though. I see bikes in those lanes getting cut off every single commute.
