It's not ease, it's efficiency: opening a locked car door is 1-2 minutes for an experienced person. Smashing the window is 2 seconds (though you also need some experience, as modern car side windows are also laminated).
The lockpicking lawyer’s skillset is not what’s required for that task. 30 seconds would be an eternity for a typical thief to just be able to open a car door. Most of these thieves take maybe 15 seconds from approach to escape. Stealing a whole car is a little bit different but nobody is going to sit there with their adrenaline pumping, wearing gloves, in the middle of the night trying to pick a car door lock that won’t even disable the alarm.
