Well, don't drive in Madison, Wisconsin until you learn. We were biking around town for about an hour last evening, and the problem out there is obvious. Some car driver gets outraged that a bicyclist is acting like he owns the whole lane and he won't move over when you blare your horn or yell at him. Car driver, learn the rules! Or there are going to be a lot of angry encounters and — I'm afraid — fights.
We bicyclists love the "bicycle boulevards," which entitle us to use the whole lane and require the motorist to stay in line and proceed at whatever speed the bicycle is establishing. But it's not so enjoyable when the motorist can't believe we have rights like this. But we do!
Drivers need to learn the rules, and the police need to do some enforcement, especially against the drivers who use their cars to intimidate the cyclists into yielding the space that has been provided to us for our safety. And bicyclists: Get out there and use those boulevards — claim the power of the sharrow! — so it become obvious that this is the way things work around here.
