At risk of causing a minor eruption in this forum, I hate the idea that their is a "fast lane" anywhere the speed limit is posted. The word "limit" means it's as fast as you can go for all lanes to which it applies -- which, in the absence notification otherwise -- is ALL lanes. If I'm doing the "limit" you should rarely have any reason to pass me, and if you have the desire, get over it. Emergencies do not include you left for work too late, you feel like the road should be posted at a higher limit, you want to arrive early so you can cut to the head of the line, etc.... Yes, if your grandmother is in the back seat bleeding to death, go for it at whatever speed you desire, but if I'm in your way don't waste time trying to communicate and waiting for me to get out of your way -- just blast around me and forget I exist. Your emergency means you don't have time to waste on my proclivities. Your irritation by flashing your high beams or getting right on my bumper and laying on the horn is probably just slowing you down more and if it's a real emergency concentrate on that, not me! But of course the vast amount of cases of such behaviors have nothing to do with an emergency and in almost no case is all that ruckus needed. In fact it may be if we all actually did the speed limit AND didn't tailgate almost all those days traffic is backed up because somebody was traveling over the speed limit AND/OR tailgating would be eliminated -- leaving all of us a better chance to get to work on time in the first place.
Well, I'm glad I got that off my chest!
