Peeves

Just venting.... When I'm trying to get high mpg it pisses me off when...
-people drive vehicles so tall I can't see the light ahead so can't plan whether to coast.
-people cut me off when the light head is red and isn't going to change soon.
-people tailgate
-people inch up before traffic is moving, forcing me to inch up and waste gas or leave a gap and piss others off

What are your mpg driving peeves?
