I think that a single train can hold over 1000 people, and requires much less energy, not to mention space, materials, infrastructure and maintenance, than hundreds of individual cars in which these 1000 people sit in 1s or maybe 2s.
Again, it doesn't matter how they are powered; cars suck as an idea; simply because of how horribly they scale. They require tons of resources to build, they require tons of resources to maintain. They eat up tons of space. They kill hundreds of thousands of people per year. They are energy inefficienct compared to trains.
Oh, and railway-based public transport systems would be trivially easy to automate, compared to cars.
If we invested even a sizeable fraction of the resources into public transport that we waste on building ever more lanes and ever bigger parking lot hells right through our cities (aka. our livingspace), barely anyone outside of actual rural areas, would even need a car.
And this isn't a pipe dream. This is how actual people in actual cities live, today. Many european and asian cities are completely accessible by public transport.
