I thought we were talking about whether or not bikes can be a massive threat to cars.
I have been paying attention in a city for a while. I have seen the situation you describe, but it's rare in my experience, even with SF supposedly full of reckless fixie-riders. Dangerous driving is far more common in my experience.
Hmm, yeah, scrolling up, there was more than a little hyperbole on both sides at the root of this thread. I agree a bike is not a "a massive threat to a car"; this doesn't mean it's okay for people to ride recklessly, or that they're not endangering others when they do.
And dangerous driving is probably more common (certainly by number of instances), and it should be condemned as well.
