It sounds weird to say, but updates being applied only in-garage doesn't mean they're not going over the air. However, updates can include software for between dozens and hundreds of individual processors. That makes them quite large. The real data pigs are driving logs and map data though, which are usually serious storage constraints in autonomous vehicles.

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.
