Re-focusing on the topic at hand here:
The answer is No. I do not wait for people around me to go away before I reach over and put my weapon on my person from the vehicle's glove box.
The only reason it is in the glove box in the first place - is usually because I am going to work or someplace where weapons are restricted in my state: Schools, Courthouses, workplace (if they specifically mention it in employee handbook).
And since I have a CC permit, and Open Carry is legal in VA, I have no problems moving my weapon from one location to another. If someone sees me - I smile at them.
I have so far done this quite often - at least once a week - there were SUV's next to me with a good vantage point on my car, people walking around and behind the car as I moved from box to hip, and one time there were 2 police cars 2 parking spaces away as I moved my weapon.
No issues whatsoever. Maybe I am subtle - but unless people look carefully at what you are doing in your car (Most folks do not care) - the sheepies will never know.
