I remember getting locked out of my 2003 Grand Marquis, and then watching the locksmith open it in about 5 seconds. It was then I realized that my door locks are a very minimal intrusion deterrent.
That being said, I imagine it's quite more difficult to get back into that vehicle.
I'd say they are meant for dumb dishonest people (and most dishonest people happen to be dumb luckily). Honest people don't need a lock to keep them out of property that isn't theirs.
They also serve as a social signal. If you unlock something with a key, you are assumed to be the owner of it by bystanders. If you bust out a lock picking-kit and start going to town, you are assumed to be committing a crime by bystanders.
Used to live literally a few blocks from there (SOMA) had my car broken into like 6x a year with nothing inside it and notes saying as such. Was such a hassle but was only like $70 Safelite trip not far away. Always wondered if they sent people out to break windows for business. You really could tell there wasn't anything in my car. Never heard of people doing it with drivers in my car though that's pretty wild.
Had my car here in Brooklyn for 5 years and it never got touched lol
I’ve seen them a couple times but I’m pretty sure a store can only have so much money on site. When you have a truck that’s visiting multiple of these stores on their rounds would definitely be a target for your ballsy ner-do-well
