That's just kind of the nature of American streets. Automobiles crash into each other all the time. That's about how much Americans care about driving safely. They have other priorities like driving better drunk than you do sober, sexting, and getting a little pregame action in while taking the kids to the birthday party at the bumper car rink. And that's a good thing. It shows individualism, freedom, and that bonafide American frontier spirit.
If you're gonna ride your bicycle on those streets it is just a matter of time before you get hit. Some guys will win the lottery and never get hit but not most of us. Does that mean you're gonna get destroyed? No. You'll probably get a little rash and some sore joints. It'll hurt a bit. But most of the car vs bike accidents I've seen didn't end up with broken bones or ambulance rides to the ER.
So don't stress it too much. And remember that it won't be much fun for your family if you need a triple bypass either.
