We won’t get railways to every door. But the title says Public Transit. So various sized rail vehicles will connect with various sized road vehicles for the last mile. Everything electric and everything autonomous.
Nobody will need to own a car in urban locations. Many places won’t allow access anyway.
We’ll all pay less for ownership. Less per mile transit. Less for goods due to reduced transport costs.
We’ll enjoy our streets as a place to socialise once the danger, noise and parked cars are gone. Multi lane highways will be replaced by parks and cycle routes.
We’ll enjoy our time not wasted sitting in traffic jams.
All this won’t stop the greed merchants peddling their lies and duping the gullible though.
