The car notifies you if an update is available, when you can postpone it, and IIRC you also receive a notification on your phone before it starts at which point you can also postpone it. Also, it tells you the estimated duration of the update in minutes and specifically notes that you will likely not be able to use the car during this time. Also, braking and steering should be dependent on software. This is the case in most modern cars, though those don't always have OTA updates. It means these can be changed and improved over time. I can definitely see someone who had auto-update not realizing their car will start the update before they need it, but I think they've chosen a decent balance between keeping users up-to-date and making sure your car is available when you need it.

That's an opinion and that's fine, but I was wondering if it was the case, i.e., they are dependent on software. > This is the case in most modern cars By `this' you mean "basic steering and braking functionality depending on upgradable software", right?

Yeah, sorry, this is definitely an opinion and I don't think I actually agree with that in general. I meant that in the case of a Tesla or many modern cars with autonomous emergency braking or lane-drift avoidance or similar, braking and/or steering is generally software-controlled, often without a mechanical default, so given features like Autopilot it "should" be software-dependent. > By `this' you mean "basic steering and braking functionality depending on upgradable software", right? Yes, but just to reiterate, most manufacturers don't use OTAs and some models never receive an update, but it's not uncommon for an update to change steering and/or braking response and feel.

A decent balance would be facilitating an interrupt/rollback of the update at any time. If you need the car now, and it's updating, it should be trivial to halt the update and operate the car on its previous software version. Storage is cheap nowadays, there's no reason to not have versioned copies of every operational software version across the vehicle.
