You have a weird dream of how people should use transportation. People like what they like. They like individual cars with 4 wheels. They don't want to share transportation with random people.

People like what they’re told to like by mass media and advertising.

Pretty sure he's sarcastically talking about trains existing

The train v car debate is for losers - cars won and will always win. Privacy and freedom will always be more important. Use trains to ship goods around, not people.

and bikes too for that matter.
