If I was a thief then I'd always hit the passenger side front door as it gives me the quickest access to the glove compartment, where valuables are likely to be stored. Not sure what the mystery is here.
Do people actually put valuable things in their glove boxes? I didn't think people put stuff besides proof of insurance and their car manuals in them. I'd think it a lot more likely that valuables were in the center console storage.
I left my checkbook in the glove compartment for like a month before realizing it. I don't write physical checks often and just forgot it was in there after needing to hide it real quick.
