You just glare at him?
I would flip off the driver.
FS has been discouraging me from doing that.... after all, a car
is a pretty deadly murder weapon, and the driver gets off lightly
if he uses it to kill me instead of, say, a knife....
I just glared at him, then gave him a snicker (short smile/luff)
becoz he tot he can acelerate and zoom past but have to jam
break...
I know what ticks off people like this... They think they
got car = king, think acelerate, ppl will run
or something, end up still have to stop for pedestrain...
This is enuff to tick him off quite abit...
Afterall no need to flip him, it's already
my victory 
But ya, I admit it's stupid to do things like this becoz some
unlucky case and the driver and ram u down... not worth it -__-
