Cycling is cheap, often faster than driving (in my city), healthy, less noisy, creates vastly less pollution, less dangerous to pedastrians...

And I'd guess that about 95% of drivers that I come across are respectful of the danger they present - overtaking with enough space, and not at too high a speed (my city doesn't have great bike lanes). Unfortunately, a typical journey involves passing more than 20 cars, which means experiencing at least 1 very close pass, or some kind of dangerous driving.

And the frustrating thing is that the drivers who impatiently pass dangerously are putting people at risk for the sake of ~10-30 seconds (or less). Often I'll catch up with them at the queue for the traffic lights.. Average traffic speeds for cars are around 8-12mph, including stopping for lights, congestion, etc, [1] which is fairly easy to surpass on a bike..
