I drove home today behind the most cautious lane-changer in the world. We were in the right lane of three, and about a mile before it ends, the guy put his turn signal on. And then nothing. Cars went by, lots of space between them, and the guy didn’t move. I did. And then, eventually, he merged into my lane, still in front of me. Didn’t turn off his turn signal, though. Still blinking, but now he’s cruising in my lane again. The left lane is WIDE open, nobody in it, and his turn signal is still blinking. We went through another intersection. Still blinking. Finally, after the left lane had been clear for at least three minutes, he moves over. I have NO idea what was going through this guy’s head. I have no idea why this is still bugging me, almost four hours after it happened. At least he used his turn signal.
