If I can recall from over 30 years ago, yes Old Faithful viewing is within a few hundred feet of a parking area. For those who naturally wander, it can be hard to understand. But a lot of visitors barely leave parking lots and pull-outs. I don't know about 95%, but I've definitely noticed this at my favorite California parks. The road-bound will take pictures at the scenic viewpoint on the shoulder of the road and at various entrance signs, and maybe use the restrooms. Then they pile back into the car to go to the next pull-out, restaurant, or hotel parking lot on their itinerary...
