> Why does everyone lack imagination on this topic?

You are right, I imagine that we should just have teleporting gates!

> if you drive to the subway

How about not driving to the subway? how about having local buses or that can take you there?

> where do you park your car

Car parks next to the station?

> how do you get to your destination once you get off the subway if it's not walking distance?

Buses or trams.

> Currently - people just drive.

Not everywhere, look at London for example.

> We could drill more regular roadways

No we can't, tunnels are expensive and bring a whole new set of problems like how do you handle an accident, how do you get to the surface etc.

> subway-like transport of passengers, or entire vehicles

That is horribly inefficient in terms of space and weight, average car weight is ~2 tons.

> powered electrically

Having it electrically powered does not mean that it's clean energy.
