All bikers better be alert. Because 99% of drivers aren't going to show you respect. I always make sure I keep a good distance away from ALL bikers on the road. I never attempt to race a bike. First off, what for? I already KNOW I'm gonna lose.

Second off, if something accidently happens, its going to be the biker that gets hurt, not me. I don't want to carry that on my shoulders the rest of my life and I don't want to see that biker get hurt, or worse.

When people get in their cars, they feel like they are in a "second home" of sorts. They get a little too comfortable. Like hypeR1 said, out come the cell phones, the kids are fighting and crawling around, gotta mess with the CD player, gotta fix your hair/make up, and on and on.
Who are the worst for things like this? Well... much as I hate to say it, most likely it would be teens and women.
NO, not ALL of them. I am going by what I have seen on the road myself. How many of you have seen the woman in front of you sit at the green light for a minute or two while applying make up and hold up traffic? Or weave in and out of the lane while combing her hair? What about the 16 year old with his new license thumping to music so loud that people 5 cars away will be deaf for life and he's in the emergency lane driving backwards because he is looking under his seat for his Dr Dre CD?
Its no wonder they didn't see the gorilla. If they did, they would have hit it!
Bikers Beware. Always.
