I am of two minds on shoaling the cars. It does feel like jumping in line and most of the time, when there is a reasonably small line I just stay in line. BUT - my vent - I'm always getting behind some yahoo that lets 4 or 5 car lengths open up in front and then floors it, making it look like I am the one holding up traffic. Half a dozen cars, it's guaranteed that one of them will do it. We'd have all been better off if I'd just filtered to the front.
