Well, I agree with waist about laws forcing you to wear a helmet 'sucking', if I could get hassled and slapped with a hefty fine for not wearing a helmet for a quick up and down test run on my residential street testing a bike simply because a cop could I'd be pissed, but I don't wear one because I have to ;-}
I know I sound like a Broken Record* about a good front blinking light being the ultimate safety weapon, my normal riding buddy Jason and I just seen it first hand once again on a beautiful bright afternoon last Friday on a ride.
Jason and I tend to ride WOT on the routine neighborhood parts runs we do, and we ride 40+MPH shifters.
Ya, it's a 'whos fastest today' kind of thing.
ANyway... we were hauling WOT ass downhill on a 30MPH road and a big pickup truck starting backing out of his driveway and it was almost magical... As he glanced our way for traffic he slammed on his brakes half way out of his driveway and waited for us to race by even though we were a good 200' away in single file when he looked.
How bright is bright enough for a daylight front flasher?
For me, when I can see the blinking refection on the reflective traffic signs ;-}
*Broken Record:
For those of you too young to have even owned and played vinyl music records, it was not uncommon for the needle or a scratch to mess up a grove in the record and cause it to skip back a track and replay a few seconds of the song playing over and over again.
Hence, it was a broken record relentlessly replaying that same thing.
