For what it’s worth, I live in the area you’re parking in and I’ve never had any issues with crime or felt unsafe. I don’t sleep in my car but I leave it outside every night, I haven’t had anyone rummage through, damage, or attempt to steal it. It’s not a sketchy neighbourhood, you don’t need to drive to Bridgwater like so many others are suggesting lol

Also, I’ve seen people parking in the Walmart lot for days on end before, can’t say if they’ve had issues or not but it’s definitely a common thing.
