Alternatives aside for the moment, what we currently have seems to be populist governments dishing out subsidies to private vehicle owners (free roads, free parking, free money for EVs). It seems to work in terms of getting elected. Yet it incentivises people to live far away from their places of interest - work, school, family and friends, and drive everywhere to make up for that.
Maybe a combination of tech will allow us to properly price things like traffic, parking, resource use. Then we may find that suburbia is less sensible economically, or that more living and working is moved out to where people are housed.
Yes, a simpler life in general. Less powerful, more connected.
