We wouldn’t accept, in any corporate environment, a computer system where the only form of authentication was a yubikey with no password, the fact that our cars essentially still work like this in 2024 is appalling.
I guess it could help with climate goals, so I can see your point.
The main problem is not that a key is enough to use a car, but that owning the car is not enough to keep others out of it.
Tesla has had multiple recall issues with the interface pad malfunctioning or not even turning on.
Meanwhile I can just put a key in my car and go. Sure, someone could steal the key - but statistically that is far less likely that a software or hardware failure.
Ofc, then you run risk of blood being taken by force, but it would be bit more secure.
Whenever people get a hard on for biometrics I tell them exactly that.
No I don't want to loose a finger. I'd rather just give them my password.
It's same as having keys tho. Authorization vs authentication.
p.s. pin to drive exists already.
Despite the tradeoffs, I think our current approach is better than the alternatives.
For example Face ID in iPhones works pretty well, and your face data is stored on the phone only.
I'm the only employee in the company. :)
