The reality is, and this is just a fact that all cars have recalls. And currently there are already lots of recalls that require software. Now you just have to go to the dealship.

At best you could argue, maybe the software is better because a bug is more expensive to fix. But that can also lead to low risk bugs not being fixed.

Either way, the solution is not to prevent update, but make the cost higher for companies if their software or their update causes anything safety critical to be wrong.

Regulation around having a separate update for security critical things might be reasonable on government level. But usually the update is not forced in if its mostly features.
