Jammed

I've never understood why there's always a traffic jam when two lanes have merged into one. No, I get that one lane of traffic must stop and put on their blinkers and wait for someone in the other lane to slow down and wave them in. Of course with everyone slowing down, stopping even, traffic will jam up. What I'm talking about, though, is after the lanes have merged into one. We've got a flow of traffic now, and there's no need to stop. There are more cars, sure, but if the car in front of the car in front of you goes back to the speed limit (or, preferably, 10 over), we can all get back to being on time to whatever stupid place we're trying to get to. Once we've merged and can all go in a straight, open lane, how about we all speed the fuck up? What are you putting your brakes on for? Dickhead.
