I wouldn't be so quick to say that - it's unquestionably more convenient than old-fashioned transponder keys in a few really important ways. You can't lock your keys in the car, you don't need more than one free hand to open a door (and sometimes not even that), and you don't need to deal with a massive bundle of keys jangling against your knees.

Honestly... As an end user, I prefer convenience over security in my everyday life. I have insurance for the rare instance someone steals it.

The same goes for my house. I could live in a concrete bunker with no windows and steel doors, but I would much rather live in a home with large windows and a door with a crummy deadbolt.

The risk of someone stealing my car or breaking into my house is low. If that risk increases (and thus the area's overall quality decreases), I'll move to a different location.

Ultimately, if it were a severe problem, wouldn't insurance premiums reflect this?

Having had it on my last few cars, I wouldn’t go back.

tumber locks are built on even more hopes and dreams than security.

proper PSK cryptographic locks can (and are) implemented for cars already, just not all cars.
