There are bad drivers out there, no doubt about it. I'm glad that I can ride mainly rural roads that have little traffic. But then there's stuff like this:

Yesterday headed home with a good wind behind on a straight and flat stretch. I was going about 25 mph and was overtaking another rider who was going about 20. Car approaching from behind at the speed limit (45 mph). We were coming up to a crossroads and the car wanted to turn right. He passed me, then realized he didn't have room to turn right in front of the other biker, so slowed way down. Sudeenly, the other rider sticks out her arm for a left turn at the same time she initiates the turns. She just about t-boned the car! Driver jammed on the brakes and lets her go, then actually started looking around to see where I was! It was clear he wasn't going anywhere until he know I wasn't passing him on the right. I wasn't - I had backed off to avoid a three-way vehicle meet-up.

I thought it was a good bit of attentive driving!
