I've never studied Virginia law,
Doesn't matter. You cited Supreme Court cases, without having studied appellate law.
but it's pretty universal that license plates have to be illuminated well enough to be read from 50 feet away at night.
Source regarding Temporary Plates?
Mounting a temporary tag behind a tinted window would've been in violation of these laws.

The stop wouldn't have been considered "completed" from a legal standpoint until they told him he could leave.
Source? [EDIT: With regard to an unlawful stop]
I have no love for cops. I've been pulled over multiple times because they claimed they couldn't tell if I was wearing my seatbelt. But it's important to know what rights you have during a traffic stop.
The discussion is not about a lawful stop, that hasn't concluded. It's about an unlawful stop; or a lawful stop that should have been concluded.
Staying in the vehicle when ordered to exit isn't one of them.
Source, as it relates to my above reply?
You don't have to follow an unlawful order.
Exaggerated Example To Illustrate The Point
If a Vegas cop seriously ordered you to do the chicken dance while you were being detained on the strip, for a burned out taillight; would that be a lawful order? Would you follow it?
In that same scenario, would it be lawful for the cop to order your beautiful wife to come sit in the front seat of his squad car with him, as you dance the night away?
Oh, so now you get to choose which unlawful orders you
"must" follow? Or do you simply just comply?
Sandra Bland
If you don't an unlawful order, you may end up like Sandra Bland. She refused to follow an unlawful order.
Her family settled for almost 2 million, reportedly. Probably would have been more today.
I've questioned/instructed an officer three times in my life, on orders I knew were unlawful. All three times, they backed down.
The Point
My point is, and was, that citizens are not required to follow unlawful orders. Why citizens are walking around believing something so silly is beyond me.
Now That That's Hopefully Clear
Disclaimer: Obviously, it is
usually better to obey, and initiate legal action later. You have to decide for yourself, based on the circumstances.
