It is probably possible to get drivers to improve if the incentives were there or if they had no choice due to external factors. I bet it would be cheaper than money spent on self driving tech too.

I'd love to see better public transit, but transit is so bad for most of us that it would take a massive investment before there is any return, and half measures won't work. You have to go all in on transit before you can see any significant change - if you invest in the wrong network you won't know until a massive amount as been invested and there is no return (leaving open the question of if a different investment would have worked).
