Mostly no… and often when they do it’s a dealer install, or they can’t upgrade much because it’s all components from 3rd parties with their own software & can’t be upgraded - Tesla have a lot of vertical integration which means they can upgrade the software of even the smallest parts OTA.

That’s not to say the other manufacturers couldn’t work that way but when you’ve been doing the same thing for 100 years it’s a lot harder to change.

I need a citation for that for sure, I know until very recently all software updates were non-OTA, meaning you had to drive to a dealership to get the software applied, which means dealers were hesitant to issue them, that could all be incorrect now and it’s certainly incorrect for some of them, I’m positive there are car companies that put out OTA like tesla, i just don’t know who they are

At least my car has updates only for the entertainment system. Other parts need service and or a full replace

For example the digital cockpit got an update with a different gauge but this apparently requires to change the display physically
