don’t make sense and you can’t back up
Wrong and wrong?
Trains are more space-efficient than cars and can therefore solve traffic congestion.
There you go. Not that difficult to grasp.
make more sense in general
That’s a meaningless statement
barely more space efficient
By barely you mean 20 fold?
The problem with having only car lanes is that they’ll always be congested, no matter how many lanes you add (look up induced demand). Trains have so much more capacity that we don’t run into this issue.
Basically, 4 car lanes=traffic jams twice a day vs. 2 car lanes + 2 train tracks= traffic flowing freely.
Of course a subway would be even nicer but those aren’t always an option because tunneling is expensive
