It's crazy to me that this is possible in the first place. Standard practice is to have a fleet of test vehicles that are effectively production except in an early release group. Or, you know, having an A/B boot partition scheme with a watchdog. Things that have been around for decades at this point. Disclaimer: Former Googler, Worked closely with Automotive.
What amazes me is that any grown up person thinks it is a good idea to update vehicles as if they were telephones Owners should have to bring the vehicle into a shop to have changes made, and they should be very rare. This lazy, control freakery of the worst kind Something very bad is going on happen and people will die before we realize that it is a stupid dangerous practice
There are a few different kinds of updates that can be applied, each with their own protective layers.
Infotainment updates, like what happened to Rivian aren't that dangerous. You lose "convienience features" like maps, air con, etc, but generally nothing that could kill you or someone else.
Then there's system updates, which is where danger noodle things happen. Automotive manufacturers are significantly more risk averse to updating these components, and generally, if _anything_ within the system looks wonky, it's an immediate revert.
If I, as a Polestar owner, wanted to get an update for my vehicle, the nearest service center is 1.5h away. If I lived in Montana (United States), it would be realistically impossible for me to update my car. Thus, if we want to enable competition within the markets, we shouldn't have regulations that force a new manufacturer to have a global network just to add CarPlay to a screen.
