Yeah, I can definitely understand that it's probably far faster (and cheaper, and reliable) to transfer the data in the shop with a USB cable in both directions.

In fact, it's probably fastest to have a small bank of hard drives that you can physically pull from the vehicle and swap out for a fresh one. You could probably pack a few hundred TB of storage into a unit that could fit in a briefcase and have it loaded with fresh map data and lots of room for logs.

You've possibly misinterpreted what I said. To gesture vaguely some more, it's not necessarily about what's fastest, but rather what involves the least human intervention. Wish I could be more clear.
