Was parked waiting for a client buying cigarettes at a gas station and was rear ended by an old fart in a metal V-8 who hit reverse instead of forward and gave it more gas when he went backwards. He straightened my spine.

I've never fully recovered from that one.

You tailgate - I will be having words with you.

I ride a mountain bike now, but when I drove, I dealt with those fools frequently on my morning commute. I would start slowing down, then resume speed. If they continued after several tries, I would lock my brakes up. No one ever hit me, ( I lived in the country and was ready with a deer crossing the road story) but it seemed to get the message across.

Would rather get there alive then not at all.

Always looking for and trying to anticipate changes up ahead. And no, not the slow poke holding up traffic - going with the flow nicely as that actually minimizes the risk.

As a cyclist / walker - I have developed a bit of situational awareness (self-preservation) about other cars as I do so. Find that extends even when I am behind the wheel of my own car.
