People don't value the lives of others. Some don't value their own. I think that's obvious.

The law says you can have the entire lane, but do you really need it? I'm not saying you don't have the right to it, but you are riding a 20 pound bicycle at 15 MPH while you are surrounded by 3,000+ pound vehicles that are going much faster. If you want to take up the entire lane and hold up some road rager on his way to a miserable home from a job that he hates then you are putting your life on the line. People aren't stable. Would you want to take that risk and gamble with your life? I sure wouldn't. If I was a bicyclist I'd do everything in my power to be considerate and not trigger others. Should you have to do that? I guess that's up for debate, but you have to remember you live in an angry, impulsive and irrational world.

Also, I'm not sure why I even have to explain this, but you can't safely pass bicycles on winding back roads with blind corner after blind corner. This should be pretty obvious. Should be. Also, how often are you in a car behind a motorcycle that is holding you up? I can't say that I've ever had to pass a motorcycle while in a car.

There are lots of idiotic car drivers, bicyclists, cyclists, etc. No one group is devoid of idiots.

Cars are a modern necessity. And the survival rate of car accidents is much greater than the survival of bicyclists who have been hit by cars. Again, this should be pretty obvious.
