Buying supercars has always been something that only the rich can do
Now that the world (mostly) accepts the tragedy of the commons that is GHG emissions, it’s not so easy to justify.

Any single automobile is not a real factor in climate change. But all automobiles (including supercars) are.
If they were taxed high enough to offset that shared cost completly or even more than that it would be fine.
... but that doesn't seem to be the plan here.
