I recently had the opportunity to try this out.
I was traveling in an old mini-van which I had bought with lawful money many years ago and which I keep up with my labor and a regular infusion of parts, but which is branded with a TENNESSEE license plate nevertheless.
I was on the great Plains somewhere in the mid-west late at night, pumping gas at a gas station which was closed but had left the pumps open for business with credit and debit cards.
I was the only one there as far as I could tell. The gas station had one light which was the only light in the area.
I saw a house about 200 yards away that had no lights on. I could not see what else was in the neighborhood, if anything.
I pumped gas using a debit card and because I was tired I decided to take a nap right there in my van.
I don't know how long it was after I dozed off, when I awoke from a cop knocking on my window and shining a light on me.
He demanded to see a DL from me.
I had the STATE OF TENNESSEE DL clipped to a sun visor pocket above the driver seat.
The driver door window was rolled down about 3 inches at the time.
I moved from the floor in the back where I was laying into the front of the van between the seats and flipped the visor against the window where the cop was so he could see it.
I told him that the STATE OF TENNESSEE issues such things (as a DL) and that if he desired this benefit he should go ahead and take it.
He said that he could not read it nor reach it there so I got the ignition key out of my pocket and turned the lock cylinder far enough for the power to come on, and then rolled the power window down another 8 inches or so.
At this point the cop was able to reach the DL in the visor pocket and he took it with him to his patrol car.
I laid back down in my nap spot.
The cop spent some time with that DL, perhaps 8 to 10 minutes.
This DL has a squeaky clean record attached to it.
When the cop came back he knocked on the window again and I got up again and kneeled on the floor of the van between the seats.
He put the DL back where he found it.
I asked him if he knew of a good place for taking a nap in the area.
He said that the gas station was as good a place as any, unless the owner showed up and asked me to leave. He added that he thought this was unlikely.
I told him that in this case I would continue to take my nap there. We wished each other a good night.
I power napped maybe 25 more minutes, which refreshed me enough so that I could return to traveling on the Interstate highway.
I look forward to exploring this concept further, as opportunities arise.
