I think the free market would provide bullet points 2 & 3. I can't under any certainty say that for a state run system. But #1, imo, would sort itself out rather quickly once the 'rules of the road' had been implemented. When people are not afraid of silly statutes dictating their speed, they will drive as fast as they feel comfortable. It will be commonplace to know that if you're in the left lane and not passing someone, you get honked at and ridiculed. It would be so commonplace that after getting honked at, the person moves over to the right lane and actually feels like an asshole for making someone behind them brake in the left lane.

Typed that out really fast and realized how much optimism I have for mankind. Please let it be true!!
