When I was a kid, my Mom would literally leave the keys in the station wagon in the driveway and our front door unlocked.
Yeah, 20+ years, still do it here. I’m in an ultra low crime location, plus our German Shepard is wary of strangers.
I lock up when parked out, also like eyes on the vehicle as much as possible, restaurant, whatever. Certain areas your spidy senses tell you to increase the precautions. We often think of what can happen at midnight in the bad part of town. We now have to increase vigilance midday in the better part of town.
Yes, may be clues with working parking lot cameras, but you end up against ‘the system’. That system is location & policies supported by local politics. Some things won’t change, at least not enough to matter for those involved.
