The problem is that fixing infrastructure for a “less cars” world will take decades. Unless you want a war-time level mobilisation, which I would personally be okay with, but most won’t give up even the slightest convenience so it’s hard to expect many would be fine with that.
So pushing EVs is the more realistic alternative, and it will also help with distributed storage so that more of the increasing level of home and grid scale solar and wind can be used at night.
