Ouch ... I had one laydown that left a lasting impression, and I'd bet not only on me.
I might have told this one here before, but ...
On an Easter Sunday morning, an idiot with his wife and kids in tow, passed me while I was driving the speed limit (35) in the right lane of a four lane boulevard; just as he was fully into my lane he slammed on his brakes to make a right turn into, fercrissakes, a church parking lot (???). Sensing the danger as he'd passed, I'd already hit the brakes, but still had to lay the bike down to keep from going over the top, and me and the bike skid further than I cared to under his back bumper.
Unhurt, but highly pissed, I extricated myself and the bike while he just sat in the car as if nothing happened. As I walked up on the drivers side, he rolled his window down, and before he could say a word I had him by the lapels of his christian leisure suit and had hauled the best part of his funky ass out the window while banging the back of his head against the top of the window frame with each tug, all the while telling him what a stupid SOB he was in a most unchristian manner, a sermon everyone in the church parking lot had not anticipated on an Easter Sunday.
If his wife hadn't started screaming, and the kids crying, I'd probably still be pounding on him ... Yep, most unchristian like behavior on my part, but thanks ONLY to the relatively low speed, and me laying the bike down, it was NOT me that he _did_ kill.
