Assume everyone is trying to kill you. And ride accordingly. You may lose momentum at times applying your brakes to avoid the eejits, but building it back up is good for you

Also, assume you're invisible. You can be lit like Vegas, but with mobile phones, texting and watching DVD's, they wouldn't see the Hindenburg parked across the road.
And if there is a close call and they're finally aware of your presence, make sure they see you taking their license plate numbers. I've suddenly gotten some panicky apologies. They don't know if a cop will come knocking on their door, or your cousin Daryl who just got out of prison.
