Loud pipes save lives....eat more Mexican food.
Seriously, glad you're OK. I got sideswiped once (no damage, though I ended up laying on the sidewalk) and that was enough for me. It's one thing to have a twist-grip and 600 lbs. of metal that will take you out of a bad situation in a hurry. It's another to have the acceleration of a Trabant and a mere 20 additional lbs. to your overall mass.
Oh, and just the idea of lanesplitting scares the bejeezus out of me. I'd never do it.
