This happened to me but a few days ago. On my way to work a lady in a VW Tiguan decided that it wasn't necessary to look where one was putting their car on an attempt to change lanes. The outside lane was inhabited at that time by yours truly. At no time did she even bother to look where she was going. Her head did not move. She just pulled straight over on top of me. The urge to give the back of her vehicle a good slap while strong, was not strong enough to override the desire to be as far away as possible from 1.7t of steel with the very personification of ineptitude operating it. Luckily for me the bike lane was quite wide and gave me ample room to retreat to. To this very second she still does not know that she was very nearly responsible for causing an accident on a main thoroughfare. She so happened to be taking the same path as I was, so I decided to keep an eye on her to see if she did anything else. Sure enough about 2 minutes later she did the exact same thing again. Changed lanes without even looking first. She did indicate though so I suppose that is something. Not much consolation to the poor motorcyclist under her tires however. Just another example to show we need to be vigilant at all times.
