I'm not too hip to the idea of mounting a holster in my vehicle. I want the gun on my person. But mine's not the only valid viewpoint, of course.
My pistol(s) will come out of my OWB holster(s) just fine while I'm driving my van. But if I had a car that wasn't so "gun ergonomic", I think I'd rather wear TWO holsters. Carry in the normal holster when out of the car, then in the cross draw/shoulder/chest whatever holster when in the car.
Car crash, carjacking, forgetfulness...all good reasons to think pretty hard about attaching the gun to the car and not the human.
Consider - If you have your gun in a holster mounted to the car, then you arrive and park and get out of your vehicle, what kind of movements are necessary to get the pistol into your human mounted holster? Will you find yourself OUT of the car, reaching in, grabbing gun, likely displaying your gun AND it's concealed places to the public, and then securing it on your belt? Even if you CAN holster it while seated in the car, I'm bettin' that more than once you'll forget and have to reach in, pull out, display etc.
Doesn't seem particularly safe, that scenario.
