This is actually extremely common across the tech industry. Backdoors are standard.

It's one thing to have a backdoor so your engineer can unfreeze someone's phone or fix their smart lights. These are motor vehicles carrying people inside of them on highways.

Horrifying - wow. The amount of photos I've seen purported as leaks from Tesla getting camera access or access to saved images makes it easy for me to believe.

I seem to remember one of the leaked images was rumored to be from Elon's own garage showing an odd item he owned at the time.
