I was in the right lane today with a good gap in front of me when a fellow to my left changed lanes inside the gap. I did not slow down immediately thinking he was going to continue his lane changes, and I got a little close to his bumper while slowly backing off the throttle. He took it upon himself to slow even more and forced me to use my brakes. Then he moved one more lane to the right to exit as I expected.
I stuck tongue out at him as I passed; he looked pretty annoyed with me...some people's kids.
