I'm sorry to say, I'm not as practical as the rest of you.
I could come up with more than a few excuses I suppose but what's the point.
I wear my helmet when it's cold, when I'm going on the freeway (noise suppression) or when I want to use my communication system. Otherwise, I just ware my shades.
I've wrecked twice. Once I did a fine wheelie and held it too long (went through a small fence and bent my toe back to meet my ankle). Another time I swept the rear end of my KLR around, high sided and cracked a rib. Neither time did my helmet "protect" me.
Harley riders rarely wear a helmet and yet most of the motorcycle accidents I hear about on the news are sport bike riders that think they are actually riding their machines on a race track (no, stupid, it's a city street)!
Most of us grew up in a time when cars didn't have seat belts - how did we EVER survive!
Sure, you can throw statistics at me but... I think most riders that have graduated to scooters have a sixth sence.
Or, you could just call me as "smart" as our president (oops, that's for a different web site).
