One of the things that has gotten better over the years (especially in Europe) is that car drivers are starting to take cyclists seriously. They are legitimate vehicles on the road. When I was cycling in the UK, I was amazed at how courteous drivers were. Even on back roads, people would patiently wait behind me until the road was wide enough to pass. Often they would smile and wave after they passed me. Not everyone is like that, obviously, but this kind of mutual respect is what you want to go for.
IMHO this idea is a huge step backwards if enacted. What are the counter arguments (the article was quite vague on the details)?
