I don't really do angry so generally go for blowing a kiss or a cheeky wink, or an exaggerated wave. I did have a small sign language and lip reading discussion with someone and their wife the other day about how they passed me too close just before a red light, I was smiley and nice and then as I shot off in front of them I lent over and held my arm out in a "you should be wider than here" kind of motion, he gave me more than enough room and got a cheery thumbs up.
