I think the Youtube video makes it look easier than it might be in real life since the driver goes directly to the Supercharger station (or what I assume is the station).

The rest area looked rather large and in the video I didn't see any signs directing the driver which path to take through the parking lot to get there. I could see someone who might be slightly distracted (or not yet familiar enough with the landmarks) driving through the gas station instead of turning right and missing the whole thing, and having to circle back around.
