As long as they are moving faster than people to their right I really don't mind if they're not necessarily going as fast as I'd like to, I'm usually poking along in the far right lane saving gas anyway. What annoys the hell out of me even more is people that will drive 30 mph all the way down the expressway entrance ramp and then attempt to speed up just as their merging into traffic that's moving 65-70 mph, causing someone to either have to slow down or change lanes to avoid them or them getting run all the way to the end of the ramp and then just stopping because they are retarded. At least make an attempt to get somewhat close to the speed of traffic before merging you idiot.
