This is the last I'm gonna post on this because we've hijacked this thread.
It sounds to me like you and others are suggesting that, by refusing to let another driver create a dangerous situation, you are creating a more dangerous situation. Is that correct? That isn't logical to me but then again, there's a whole lot of people incapable of using logic and they drive cars every day.
What I'd really like to see is a lot more unmarked cop cars on the road and give massive penalties/license revocations to people who a)drive at highway speeds and don't leave the appropriate amount of space in front of them, b) people who are "lane jockeys", c) idiots who ignore merge lanes and drive with one car length or less in front of them, d) people who refuse to turn on their headlights in low light conditions "to save gas" or "because I can see fine" and, of course e) anyone multitasking while driving in traffic (phones, makeup, eating, etc).
They'd make alot of revenue that way and maybe people would start being a little more considerate of their own driving habits. It would also keep the cops (incredibly, by my estimate) busy instead of them sitting on their asses most of the time so taxpayers dollars would be well-spent.
All the revenue acquired could also be used to improve roads. Ah, but I dream ....
