They are all in a single replaceable until under the hood.

Sounds more expensive? And doesn't tell you where the issue is, unlike a single burned out fuse?

Same can be said about any body control module on any ICE car. ICE cars have more modules than Teslas AND they also have fuses.

>more modules

More modules that can be replaced individually or used to diagnose a problem is a good thing.

If an ICE car had all the fuses in a locked box (which required replacing the whole thing when one burned out) you would correctly identify that as a negative for the end user.

I'm sure there were reasons why they went for the alternative at Tesla but "easy to work on" wasn't one of them.
