Not trolling it just makes sense. It's more efficient too. If we build and maintain a robust transit system then the need for this tech will be over. Batteries aside cars these days are full of plastic and other non-biodegrable materials, as cars are replaced the old ones just fill up junk yards. Not to say that trains of buses wouldn't fill up junk yards too but usually there is a large difference in build quality and durability between cars and buses.
