I don't agree with peacefulgary's opinion either.

True, at those moments he mentions it isn't useful, but that hardly means it isn't useful to have along. The time besides those mentioned, it's available, which is far preferable to it being hundreds of miles away (or even across town). Same reasoning as to why I always have a rifle in the truck, not just when travelling. Bad things don't always happen when you're at home, so whatever whiz bang hardware you may own, is profoundly useless if it isn't available when needed.

Arms can be secured to varying degrees in a vehicle. Use your imagination and google skills. A bike cable and lock run around a seat frame and locked to the gun is one simple way. Gun lockers or safes designed for vehicles also are available. A large dog in the vehicle also seems to discourage people hanging around and getting too curious.
