Now, as a motorcyclist who has been hit head-on more than once by drivers who swore "I didn't even see him!" -- with the last crash leaving me with multiple broken bones and an inability to walk for several months -- you better believe I now have both a pulsating headlamp and a nice set of loud ass pipes (they're even called "Street Cannons")! on my bike.
I've also lost a non-zero number of friends due to folks who swore they didn't see them.
It's now been eight years since I've gotten hit... so I really am sorry if my headlight or pipes bother you as I pass by but, well, I have loved ones I'd like to see again so I hope you'll forgive me.
