Has or does anyone use the Fobus Rotoholster with the mounting arm for use in the car, bedside, etc.?

I thought about it for use in the car for added comfort in the car so I don't have to drive around with my gun on my hip. Especially for longer drives.

I also thought it might work well for use at my bedside. My nightstand does not have drawers and I don't have a convenient place to keep my handgun close by while sleeping.

I also found this RAC lock:

Has anyone used it? Thought about using one next to the bed for the shotgun. And one in the car for times that I have to disarm. The glove bok is just too easy to pry open and a cable locked gun safe under the seat or in the trunk just doesn't seem that secure to me.
