I don't carry on body in the car because it's just too hard to get to the gun, especially when I pocket carried a Smith 36.
Whatever I'm carrying, it goes in the glove box when I'm driving.
There used to be a bunch of inane restriction on car carry in Ohio. They're all gone now for people with CHLs.
As a matter of fact during the debate prior to rationalization of the car carry provisions, the Ohio Highway Patrol said people would be able to drive down the highway, twirling their pistols on their fingers. I think I'll try that next...
