If you believe there is a single "best" mode of transport for all situations, you should read up on transit planning. All modes have tradeoffs. Trains are good for moving large numbers of people between fixed spots, but they have immense capital costs and can't be rerouted to meet changing demands in where people live and work without further great capital costs. There are tradeoffs even within the design space for trains between, for example, number of stops and overall top speed/transit time. I happen to like trains, but they're not the answer for all transit questions.
They're not even "objectively the best" in big cities, which is why cities have buses, cars, bicycles, and often several different kinds of trains ("heavy"/commuter trains, subways and/or elevated trains, and light rail/trolleys/streetcars/trams/whatever they're called today). Private cars are not the problem, they are good solutions for certain transit problems even within dense urban areas.
