Cars are also just a horrifically inefficient mode of transportation.

Takes up tons of space on their own. Add in the tons of surface area that mostly sits empty, paved, and impermeable waiting in case someone wants to park there. Add in the maintenance of roads, intersections, bridges, tunnels, and other infrastructure. The energy involved in moving thousands of pounds of metal in order to move, most of the time, just 1 individual with very little cargo.

Really doesn’t matter if it’s gasoline, electric, hydrogen, ammonia, solar, diesel, bio-diesel, nuclear, whatever. Personally motor vehicles have a ton of issues beyond the energy source.
