Forget it. They'll just smash the window and replace it, or haul it onto a flatbed and work on it at their leisure.
Are you sure the thief won't just move onto the next car whose door was left unlocked?
The trouble with smashing windows is, they're made out of tempered auto glass and can be rather resistant to having projectiles thrown at them; it's also possible to reinforce the windows so they can't be smashed very easily, even by lobbing a brick at them.
Also; they make it very obvious in public that you are attempting a security defeat by a thief, and it will look suspicious to be driving around with a big hole in your window. Noone wants to smash their own window, and now you'll have a huge mess to clean up.
