Harley bikers, (the real ones) not dentists with money and a AAA card, but guys who really ride, are super cool people, show them respect you get it back, ride at all, they are cool. A bit course, but will do anything to help, so long as you don't look down your nose at them. Sport-bike guys, NOT all, but many tend to be jocks who never grew up and have something to prove, but never had any real issues with them, too busy lane splitting, driving reckless to even see me.
The real danger is regular traffic, blind to all but their e-mail, twatter feed, face-book or wherever their "online persona" is besides going down the road. I hope our new law nets millions in fines from the screen people. :) I hope many lose their Dl and slow their roll a bit. Fingers crossed.
