Ah, thank you.

I'm pretty sure the OTA updates use the owner's home WiFi... which is likely to have better connections than an in-car cellular service and is less likely to have data limits (in the US at least).

Oh... I hadn't realized that the applications themselves could pay potentially pay the owners for the cloud computing. That's a super interesting concept... I think it could be super hard to do technically, but I'll be super curious about the pricing to see how competitive it might be with AWS, Azure, etc.
