So here is a question. After reading the last couple posts about some of our brothers getting broken up at intersections (Godspeed on healing to them) is there any other advice other than, lane position, covering the levers, head on a swivel? "
When riding, do NOT ride looking through your own visor or windshield...
Learn to ride looking through the rear window and windscreen of the car in front of you !

Ride according to what that driver sees !
Have you ever cussed at the cage that swerved into the middle of the road just as you were preparing to overtake?

You never noticed the bicycle rider in front, or the little boy chasing his basketball down the driveway, did you ?

THAT'S why the cage swerved !
Also...
In the rain, lane paint may become very slippery, avoid it like they were made of wet glass...
In the rain, cars will raise a LOT of water when splashing their way through puddles - learn to ride with zero vision for a second or two, i.e. don't panic and slam the brakes, just ride on like nothing happened... ride through the splash and you'll be still riding as you come out the other side

WET but still ridin'...
Personally, I always leave a distance between myself and the rider in front, unless I have to overtake; enough distance to avoid him if he slams the brakes or does something stupid...
GOOD helmets have a quick-release chin strap; learn to release it with one hand only, learning from both hands (your thumbs will be on the opposide side of the strap...)
BETTER helmets have a red tab you can yank to release in an emergency.
BEST helmets not only have all the above, but your chin won't rub into the chin piece, your ears aren't pressed shut, your forehead is completely protected and the back of your neck is also protected.
Rule of thumb is "no drafts anywhere!"
And... never ever challenge superscooter riders, they will outrace you in the straight, then slow down like old ladies into the bends...

Ride well, ride safe !
