"That's harder than it sounds."
Is it, though? Is it really? We've been making manual car door latches for 100 years.
It's only hard for Musk, and only because he just doesn't want to do it.
The point is that the entire passenger entry system has been designed around electronic door handles. So you might think it's as simple as just swapping them for mechanical ones but it's not.
The handles are really just buttons. Requests to a computer. The "locks" are just a binary state of the entry system that determines if conditions are satisfied to release the mechanical latch when the request is made.
We've had electronic door locks with manual override for... 3 decades now?
We're not talking about door locks, but door latches and handles. There are no "locks" on Teslas. As I said "locked" is just a state in the computer.
Seriously. Every other car maker has figured out how to make normal door handles. You can even buy the parts directly from them if you find it too hard to design yourself.
Again, what did they miss? Spell it out for us, please!
