Sorry that was ambiguous.
I should have said the cop can't see whether or not you have a driver's license therefore no RS or PC to stop just anyone driving down the road.
But it seems you want it both ways (which is where court precedent comes in.)
You say: "If you open carry, PC is achieved on sight, and the officer can require license verification."
However, you also say: "If you drive down the road, no PC is achieved."
When in reality doing both those things (driving and carrying a handgun) are illegal unless licensed.
Why is one different than the other?
