The point of the parent was that for commuters, for long-distance cargo transport and for busses some "super lane guide" would be useful.
Does your going into the mountains contain "driving on the same lane with thousands of others from the same place to the same place every day"?
Because that’s what I was suggesting – nothing more, nothing less: Replacing mass-scale commuting with rail.
Yes, if you drive somewhere where no one else wants to go, cars are still useful – but if you’re going the same path that another million people are also taking, maybe rail might be better.
Rail and Road are not exclusive, they can coexist.
