double standard

if your uncle can keep driving old, low efficient, highly polluting vehicles why can't a rich person buy a ICE ferrari?

Makes much more sense to charge on "pollution/gas usage"

Kind of wealthy tax but without intervening in the market and picking winners or the "right solution"

Because the general expectation (and current reality) is that old cars will break and be scrapped eventually. Only few remain and those few don't matter in regards to global emissions as they are mostly not daily drivers. They instead contribute to keeping tiny bits of history alive.

I'd compare it to old houses which are often designated as landmarks. We don't demolish them just because they are not energy efficient by modern standards.

“We allow this thing that existed before the rules were made to continue to exist” and “we won’t allow only rich people to create new rule breaking things” is NOT a double standard.

Why are you trying to position high end sports car owners as oppressed?

"gas engine ban"

I don't know the rules in every country, but to get the exemptions it's generally required that the vehicle isn't used much — driving only to shows or museums for the biggest discount, or limited to a fairly low annual mileage.

That will continue to be the case for old cheap and expensive cars, and we justify it to preserve industrial history. There's no reason to introduce a similar exemption for certain new cars.

Ontario has historic plates ... lots of rules but generally what you just described.
