Ok, driving beaters, it wasn't all that uncommon for me to either be pulled over for a light that wasn't working quite right (last car I had, first night I had it I pulled all the bulbs and reseated them in the sockets, then properly seated the sockets in the housings because that's what got me stopped more than anything except speeding in my younger days) or have one pull up while I was working on something.
Procedure was, keep DL and CHL back to back in the wallet with insurance between them. If stopped, turn on interior light, get wallet out and slide the stack out with both hands above the dash, (at night, just keep them in the area lit up by his takedowns) and hold it CHL up in left hand on the wheel, turn key off with right hand and put right hand on wheel. He will look at your hands as he walks up.
If out of the car, most didn't bother to ask for ID, but one did. I told him I had my DL and CHL in my right inside pocket, and my revolver in the left inside pocket. He just asked me to hold the vest open with my right hand while I got the wallet out with my left.
One time when stopped, I had a PT-99 on my right hip and wallet in right back pocket. Two DPS troopers in the middle of nowhere, appeared to be FTO and trainee. Obviously senior officer asked me to step out and around to the far side of the car. (Actually fairly normal for some troopers to get you where they aren't standing in the road.) He then had me face the car, put his hand on the gun through my shirt, (tuckable Crossbreed) and asked me if I could reach my wallet like that. I could, and all went well from there. I think he was bladed toward me with his left hand on my gun and his right on his own, plus having the other officer about 10 feet away to my left, so a fairly effective way to handle the situation without the hassle of a disarm.
Only been disarmed twice; the first just left the gun in my driver seat (had been in the center console due to a long drive) and asked that I not open the door until he drove off. (I had pulled into the parking lot of a closed business when he lit me up, so no issues with leaving me wandering around on the roadside.)
The second was after my violent drunk ex BIL called them on me for shoving him out of the way to get out the door. After everybody was separate and checked, they got the details, gave him a lecture on the concept of unlawful detention and the reasonableness of far-from-deadly force to stop it, (He even admitted putting hands on me first, to keep me from leaving until he was done berating me for "not being man enough to fight him." Yeah, real genius considering I also had pepper spray and a moderately nasty crenellated-bezel tac light on me at the time.) and my neighbor and longtime friend of my mom's side of the family was actually the one to casually hand my .357 back to me with the cylinder open and the loose rounds in a baggie.
I palmed the Comp I speedloader from the outside pocket where I kept it, (actually did think it a bit odd they pulled that out, looked at it and put it back during the initial patdown) popped it on hard enough to release the rounds just the way I'd practiced hundreds of times, and closed the cylinder as I reholstered in the Coronado vest I was wearing, then started refilling the speedloader from the baggie. We kept talking about the idiot BIL, and as I went to do the push-and-turn to lock the rounds into the speedloader, he glanced down, stopped mid sentence, and switched to "did I really just completely miss you loading your f***ing gun right in front of me while we're still standing around with half the local PD finishing up?" I said "well, you didn't tell me not to when you handed me the gun and ammo, so I figured you weren't too worried about me being armed right now." To this day I'm still not sure if the head shake was for me loading up right then or himself for not noticing until what would have been way too late if I'd had hostile intent.
