I normally ride vehicularly, take the lane when I need to etc. However, yesterday I had a close call that showed that sometimes there is nothing you can do.
I was riding down a road at about 27MPH (its a slight downhill) in the middle of the lane. I had given the car ahead of me lots of space. He slows down and has his left indicator blinking (the road is wide enough that two cars can travel abreast, in fact, it almost has a turning lane) and moves all the way to the left. He has left a space wide enough for a car or a truck to safely pass on his right. I continue straight and right before I pass him on the right he decides to take a RIGHT!. He guns it and goes straight and veers right into my path. It seems that he was intending to pull into a parking lot on the left until he saw a parking spot a bit ahead to the right.
Here I am moving at 27MPH. By the time I realized what this knuckle-head was pulling I had two choices
1. Grab a handful of brake and hope to stop. However, by virtue of how fast he had cut me off there was no such chance of me stopping before he sideswipes me.
2. keep going and swerve right and hope to squeak by the idiot and the parked cars on the right.
I passed him with about 1 inch between my handlebar and his mirror. I was also a couple of inches from the parked cars on the right. I was yelling bloody murder but it wouldn't have helped. He actually almost clipped my rear wheel.
I kept going but I was tempted to loop round and go berserk on him for almost killing me. No matter how much you prepare and watch out, you will always find the driver who does something so boneheadedly stupid that there is almost no way you could prepare for it.
