Why are OTA updates so expensive? The price isn't prohibitive in other fields. I don't see how adding more cars would make that process more expensive, as if anything I'd expect a lot of the cost to come from QA and with more cars that cost gets spread out better.

I'd hazard life critical systems requiring a greater degree of assurance that the software update actually arrived at it's destination. Maintaining connectivity to a great number of network end nodes is not a trivial endeavor, even before you get into them being able to move around.

But who am I kidding. Someone probably just pays pays for a SIM to embed in an ECU with remote wake-up to phone home and grab an update, and the cost comes from all the telco networks that need to be contracted with to forward the traffic back home.

You also have to factor in that there's a chance of OTA failure, and the failure probably requires a mechanic visit at the manufacturer's expense.

You need to guarantee it happens.

So you can't just use Wifi, you need to send it through the cellular provider.

Also it only gets expensive if you are doing it to millions of cars, Tesla doesn't have millions of cars. And also Tesla is using investor Money.

They don’t guarantee things happen or not happen. They don’t care. That’s their secret.

Since more than a year you need to connect to Wifi to get new updates.
