Whenever I am behind someone who does this, I crowd him/her in my tall pickup, makes them think I'm in their back seat. They usually begin to creep forward, while watching me continuously. I move up also, until they're at a reasonable distance from the car in front of them, then I stop.
There is one old dude driving a vintage early 60's Impala that I really enjoy coming up on him. He rolls down his window and angrily waves me back, which I blissfully ignore. I usually wave at him when the light turns green, while he shakes his fist. Makes my day.
I bet you get invited to a lot of parties.....................
