The thing is, we already have the solution though. It's public transport. Railways can also be used to transport cargo. For longer routes you can still use ships.
Your solution is the unrealistic one. Because we would have to invest an insane amount of money into that infrastructure. We could invest a fraction if that into public transport and we would be so much better off.
I don't care how many scientists agree with you. Just think critically for like 10 seconds about this. How would this really improve anything over public transport?
Also there are a lot if scientists agreeing with me, so...
