Sure, I'm not telling anyone not to lock their car doors. You don't have to make it as easy as possible for someone to steal your belongings in order to understand that some measures will do more harm than good. There are solutions which aren't part of either extreme.

A friend of mine had his car broken into something like 4 or 5 times in 6 months in an underground gated parking area at his apartment. Each time they would break the side window to get inside the car. They would do this with half a dozen cars at a time.

It wasn't a particularly bad part of town, but the entrance to the parking area wasn't in a high traffic area and there was some green space nearby making it pretty easy for people to sneak into the parking area.

He eventually just stopped leaving anything at all in his car, rolling down the windows, and leaving it unlocked. As soon as he did that, the thieves would simply move onto the next vehicle without damaging his. Once most people started leaving their windows rolled down, the thieves stopped visiting to move onto more rewarding victims...

So sometimes the solution is to not lock your car doors. :(
