I don't agree with a ban, but burning crude oil (are you sure about that, it's usually refined at least a little?) can have centralised carbon capture and filtration, whereas cars pretty much just pump it straight out. Luckily they made the smoke invisible so it's ok, almost like it's not even there!

They don’t even unload it from the tankers. Absolute crude. Seen it with my own two.

Exactly, as long as no one sees it, it isn’t happening. Same with them burning plastic and trash.
