Also, we'll have to tear down the majority of the houses in the US, and build new ones in an arrangement that allows for bus lines to have sufficient passenger density to be less polluting than cars.
EVs are better than ICE cars for the environment and public health in every way possible. Also, there's an incremental path forward that we can take right now.
I wish there was better public transit in the US. Heck; I wish California would just mandate minimum density for new development near transit stations, and also auto-approve any compliant permit applications for housing in those areas (bypassing local zoning reviews, etc, etc.)
Sadly, that won't happen while the current generation of politicians is around.
Around here, they're mostly focusing on blocking construction, narrowing roads and cutting transit options. I think they're doing it to further prop up housing costs in wealthy neighborhoods.
Meanwhile, in Atlanta, private school children ride our trains every day, often with no adults, to Woodward academy. Public school children do too, but they're not wearing identifying jackets.
Or Japan, or much of Europe (especially, Spain, Germany, Amsterdam, Austria) where students rides busses, trams, and trains every day.
Most of these locations are also known better for physically disabled or elderly.
No matter how well developed public transit may or may not become across the nation, we're still going to need private transit.
