Its hard to imagine approaching an intersection, and at no point during the approach and turn, not looking forward or in the direction of the turn, yet I encounter this every day.
One idea would be to start making people more aware of the penalties for such maneuvers and aggressively prosecuting them. Such a thing would surely qualify as reckless operation, which can be a felony conviction in some jurisdictions even if no one was harmed.

Isn't that what the process of going to the DMV is? A test of your patience and mental fortitude? I kid, but I really dislike this idea. It seems nearly impossible to objectively measure, and too prone to manipulation. I fear that it would end up being used as some sort of a modern day poll tax.
I really think that the test to get a license should include some kind of screen for impatience, irritability, and aggression. I imagine we could come up with a reasonable way of screening out people who are prone to such behavior.
