Learned this one from an old biker: The Right of Weight will always win.
That's a good one. See also: "'He had his turn signal on' won't look good on your tombstone."
Seriously. That's how I've always described it. I drive a large vehicle. You will lose. Get out of the way. Use common sense and move. I like that. I'm going to put that on my car: "Yield To Gross Tonnage". Good shit.
It's not actually supposed to be a call to break the law...
It's a pretty good bumper sticker, though. It's like Pax Propter Vim. "Yield to Gross Tonnage".
