I’m not arguing the philosophy. It’s a wonderful idea. As someone who regularly drives a stick shift I very much wish that it would work. But like many wonderful ideas it doesn’t survive contact with actual humans. In any large city if there is a car length open in front of your vehicle then someone will be zipping into it. I’ve had people do that while we’re traveling at 65mph let alone in slow moving traffic. If you keep sitting there and letting people go in front of you until there is room then you will not move and you will probably get shot by one of the people stuck behind you. It’s like if you were at the grocery store durring a busy time and you kept telling people to go in front of you then you wouldn’t be able to check out until everyone was gone.
