Had the same feeling a while ago, I called it the teleportation effect. From the moment you reduce the time needed to go somewhere, you alter the experience to a point that it's not recognizable. Not to say that it's not nice to see the mountain from the sky for one hour but it is an other thing to go through them.

Something to break the teleportation is obviously to make breaks and enjoy where you are (a lake not too far on the road, any viewpoint...). Plan in advance, have a tent, be ready to not reach your target in one day and you will enjoy a much better a road trip than a train, a plane or even the highway.
