The car gun, why?
I'll be honest, I just never really got the idea of the "car gun" or the "car rifle", for "most people". ("Most people" being urban/suburban dwellers, which statistically speaking, is "most people".)
Now if I lived in a rural area, where police response is measured anywhere from 15 minutes, to hours, and/or no one else is around to even call, I had the potential for opportunistic shots on varmints/predators, a sudden hunting/plinking opportunity, or to put down injured animals etc. it makes great sense.
However, I just don't see it making sense in an urban/suburban scenario, if I've got a CCW on my person, and I have the opportunity to run to my car for a rifle, I've got the opportunity to get the hell out of there too.
Don't get me wrong, if you can do it legally in your state, more power to you, if you're a gun owner at home, or on your hip, I see no problem with one in your car too. I want to like the idea of the "car gun" very badly, I just don't know if it makes any sense for most people from a purely pragmatic situational standpoint.
Except for rural dwellers, (which perhaps, you all are) I just can't fathom a scenario where I'd be able to bring a rifle into play, where I couldn't just use the time escaping.
