- If it's not a "recall," there isn't much of a government paper trail for consumers when the OTA update goes awry. You don't even know if you should have such and such version of the software, and if the patches are non-linear then it's non-obvious even to experts examining your car's current status whether it's been applied or not.
- OTA updates for cars seem fraught with peril. Have you ever seen a bricked Tesla driving down the road? It's terrifying. Have you ever been the driver of such a Tesla while not in cell range? It's more terrifying because you don't know if the charge will last till you have cell service or what will happen if you're stuck in the middle of nowhere. Did they ensure the update would only apply after you've turned the car off and on again? Even if they did, if you drove your car and the steering/brakes/gas suddenly behaved differently, do you think you'd be more or less likely to crash? Whether they can technically solve the thing with an OTA update or not, it seems prudent (not that it's happening yet) to force people to make a proactive decision to opt in to the change.
