> But I don't understand what closing the windows all the way vs leaving them open a crack does for security?
Because security is about having slightly higher security than the other person.
It is a game of "you don't have to outrun the bear / swim faster than the shark, you just have to be faster than the other person".
And open car window lets someone easily get in without breaking the glass and attracting attention and the cracked open window may give them the idea to try it in the first place.
The locks on your door are also nearly useless against someone with any lock picking skill at all, and your windows can probably be easily broken, but thieves are more likely to come in through an unlocked door or open window.
And these days with immobilizers, the cars that have them aren't often being stolen by hacking the CANbus, they're being stolen because people leave them idling in the driveway with the fob inside the car and the thief just hops in and drives off--possibly with the kid in the backseat.
If you lock your doors, roll your windows up and don't leave your keys in the car you will have left problems with theft and burglary. You won't eliminate it, but that doesn't mean those precautions don't work at all. Security isn't a binary either-or where you either have perfect security or none at all.

I get that, but I just don't see the security disadvantage of having a 1 cm gap between the top of the glass and the bottom of the window frame; that's what I'm asking about.
