How about the people who are zooming right along, and then they get up to your car and all of a sudden slow to your speed and stay right next to you?
And my favorite - when they speed up to get in front of you, then go slower than you're going, forcing you to take evasive action.
Then there's PARKING. But we'd better not get started on that one yet. I've got a lot more messages and memes to cover today! :-)
