While we're on the subject of maps-related bugs, I was recently borrowing a new Tesla Model Y and took it on a RORO ferry. After the crossing, the car’s GPS was convinced I was still at the port where I had departed from. I restarted it a couple of times, but nothing. I drove off using Waze on my phone instead of the car's navigation. The map on the car kept moving relative to the direction I was driving, so the navigation was showing me driving into the sea and eventually started complaining that it would be impossible to find a charger.

Approximately 5 hours later, just as I was about to arrive, the car finally managed to figure out my correct location.

Exciting trip, not a huge fan of Teslas, but their charger planning is really nice. It was very unpleasant to suddenly lose it.

I just genuinely wonder how such a bug can actually occur, surely you'd update the GPS fix more often than every couple of hours. Hard to imagine the car just suddenly couldn't get a GPS fix for hours either. But if it did somehow totally lose the ability to use GPS, the car must have a pretty good dead reckoning system given how well it was responding to my changes in direction.

On a vaguely related note, driving 3000 kilometers through Europe in an electric car was surprisingly nice. Certainly didn't affect the length of the trip nearly as much as I'd have expected, but it was certainly super annoying to try and figure out the optimal rate of travel on the Autobahn. Charging at Tesla's supercharges was vastly more expensive than I expected, the "fuel" costs weren't much lower than what you could easily reach with a diesel car.

It is easily 29,905 road miles away. If you put all of your blood vessels end to end they would go to the moon and back.

The flight distance is 2,520 miles, Google puts road distance at 3,179 mi = 1.26x, 29,905 mi is 11.87x. Road miles are not even close to accounting for it, it’s just a bug.

Possibly it was using WPS keyed to the ferry's WiFi and didn't consider the possibility that the ferry itself could move out of where it was registered (ie, the port)?

The moon orbits too quickly to make this practical

I drove away from the ferry and passed lots of WiFi APs on the way, presumably it should have figured out the new location pretty quick with WPS.

context?

The distance is more than the circumference of the Earth. If you wrapped a rope around the planet at the equator, the length would be around 25k miles.

Sure. However, if the road around the planet goes to Everest and back, the total length of travel will exceed the circumference of the planet.
