You could choose a scenic route or a fast route. The scenic routes would be slower and there would be considerable separation from the other coaches on that route so that the views from the windows, especially the front would be unobstructed. The view downward and forward would no longer be one of an expanse of asphalt, but of the earth used for a better purpose.

The view from scenic overlooks could be right up to the edge with natural screens separating one overlook from another.

There would little need to make deep cuts in the hills or fills in the valleys for a roadway. The length of the supporting pillars could be adjusted to make up those differences.

I personally would like to see the route chosen and my progress along it displayed.
