Motorcycle and Scooter appreciation

Saadat has the right of it here, I was simply interested in whether I was 100% going to lose in this situation, or whether there was an achilles heel known only to motorcyclists that might even things up a bit, as unlikely as that sounds.

I would always council Zen-like calm on the roads, as two wrongs don't make a right.

If I didn't, though, I'd say engine kill-switch. Usually big, red and accessible on the bars. Just make sure you're in position to get the fuck out of there pretty swiftly afterwards, as you've only got maybe 5 seconds grace before you've got a very angry biker all over you.
