Earlier quoted context omitted.
> Neither the biker nor the driver in the OP's post are in the wrong In the OP's situation, the drivers that exhibit aggressive and dangerous behavior are clearly in the wrong. You could argue that their frustration is understandable, but their behavior is certainly wrong.
So is the guy who steals an unlocked bike. What are you going to do? You're going to not create that situation in the first place. You're going to use a bike lock. "Share the road" is a dumb solution, as evidenced by the OP. It simply does not work . Find another solution.
Share the road works fine as a solution without dramatically overhauling current infrastructure. Just don't be a mean driver.
