I laid down my bike last year and slid across the wet pavement. My head hit a stop sign pillar and snapped pretty violently. I had a headache, plus a broken collarbone and four cracked ribs, along with a cracked helmet. I'm not a quad. I don't have a six-inch crack in my skull. And I'm still riding. I don't like helmet laws either. BUT PLEASE: Wear your helmet. Ride responsibly. And assume that every driver on the planet is out to kill you.
You're right. But some of them actually are. Some of them are (subconsciously) jealous of the freedom of the motorcycle rider. (jmo)
