Ok, so if I read that right, you want to make sure that it IS concealed? No matter what you're trying to do with it, it really doesn't matter while you're driving down the road (this is advice that I received from, believe it or not, a State Trooper). The location of the gun really only matters when someone approaches your vehicle, most likely when you've been pulled over.
The gun being (I'm assuming) holstered on your right side, between yourself and the center console, would be considered concealed as far as I know. If you're at all concerned, you could always make sure your shirt was pulled overthe gunif/when you get pulled over.
