Your bike lanes must be wider than the ones here. There is a stretch of bike lane down the hill to the station where I go in the mornings. It is just barely the width of a bike. Cars here are not keen on letting bikes past, even in the bike lane and will pull over as far left as they possibly can so that even bikes have trouble slipping past in the bike lane. And although it is a one lane road, cars will double up into two lanes well before the t-intersection at the bottom of the hill so that I end up having to go on the sidewalk to get past. And I find that the big SUV's are the most eager to squeeze bikes off the road. They even inch further over when they see you coming so you have no way of passing.

sorry for the rant, but drivers here are terribly inconsiderate.
