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
And making train tracks across line distances is also expensive. Why would the government spend money there instead of something like the failing school system or defending the nation or trying to help with the huge issue of homelessness.
