I think maybe they have to "report in" to Balzers Castle after measuring. I think it may be posible they pick up the mopeds at Schaanwald, then go back to the border crossing and start measuring...........then end measuring at the Balzers border crossing. Then go to Balzers Castle to turn in milage and moped and get route info to Zermatt.
In that screencap of Jennifer at the Balzers border crossing......it didnt look like there was anyone there to meet her or to turn in the moped too. That might take place at the castle.
That location of Jennifer and Justin on Reitstrasse, to me, looks like they are trying to find their way up to the castle AFTER finishing the measuring.
This seems to be the most likely thing. The route I laid out was based on the promo map thing, but the map that Vyxsen is holding goes border to border. (That makes sense if they're measuring the length.) Their route is a little different from the one in that video which goes from the bridge to Sargans (as can be seen in Neobie's map) to border crossing near Schaanwald (right start point). And the small red/white circle is probably where they go pick up their mopeds as was speculated. Google says it's 10.3 km from border to gas station, so Gary would be quite close. Maybe they forgot to measure the zillion roundabouts.
Either way seems way closer than Jet's 17km and hopefully that means good things for Gary and Mal Mal.

peach if the castle is where they go after the measurement, would both team members be going up there as we Jet and Cord doing in the earlier cap? Now that I think about it, that's similar to first roadblock in that they finished the puzzle and then had to go and give the answer as a team and I'm sure there are a lot of other similar examples, but just seemed a little odd.

And now I've the Lonely Goatherd stuck in my head. I think it means only one team gets U-Turned.
Just kidding. I've not thought about it much.
