Damn dude. Glad you're ok!
So far I've been lucky. The closest call I've had was doing about 40mph on a 4-lane commercial area. Lady was pulling out of a parking lot turning left, heading my direction. She shot over all three lanes, right into my lane.
Slammed on my brakes, locked up the rear, and slid towards the curb. Luckily, I was able to let go of the brakes just before I hit the curb and keep it on the wheels. After I had full control, I made sure she knew she was #1.
For one, I understand that people just don't look where they're going. But what almost drives me more nuts is that people don't understand the common rules of the road. Under no circumstance should she have shot over to my lane. Rules state that you must take the first open lane, and then merge when safe.
Oh, and speaking of laying it down with gravel, I puckered up a few weeks ago when I was going around a round-a-bout, and I ran over that tar-like patch-job on the asphalt. My tire slid the width of the patch, which was about 6-inches. Was like ice. I thought I was going down for a second.
