Why does it have to be one or the other?

I'd absolutely love to see more high speed trains! But most of the stuff I use my car for is local transport. A train would be of absolutely no use for that.

(And I already try to keep it off the roads as much s possible, by using public transports instead.)

Trains should be developer as the better option to planes. The car problem needs completely different solutions.
