Did you read the book, One Second After? The protagonist’s mother in law had an older car with no electronics and they were able to drive around unmolested and there was a hippie clan in the woods with older VW’s and no one raided them.
But I do wonder about a real life situation as you described.
Further on in the book, didn’t a local elected official attempt to confiscate the car?
That was pretty accurate, btw....
There will always be some “authority figure” assuming they are entitled to your stuff.
