Yeah, I get that. And my point wasn't that this is wrong or controversial, it's that they chose shit data that doesn't prove anything because they wanted to chase the biggest possible number instead of actually proving their point. I am not attacking you. I am not attacking the notion that 2m wide cars are a bad thing.
I literally had a co-worker look over my shoulder and say "So fucking what, Range Rovers were huge in 1980 and we complained about the size of them then". Comparing a MkI Golf to a RR gives no context whatsoever. All they had to do was compare a 1980 RR to a 2022 RR to a current B-segment hatchback and the point would've been much better made. What they did instead was look around for the biggest and smallest possible things, think "wow, that's a big number" and throw them together. But it proved nothing. I could say a brand new Fiesta is smaller than a Ford Granada from the 80s and that would make just as much sense. None. And I still don't know what the fuck the horse carriage was meant to prove. I have zero issues with "The Disco (and it is a Disco they used, not a RR but I feel the point stands adequately with it because the RR was their largest in 1980 and the Disco is their largest now) and its like are too fucking big". They should have just stuck with that.
Stupid, cherry-picked stats don't help an argument, they hurt it. If you use facts to slam the opponent, make sure they're both relevant and correct or you've just wasted your time because one little error renders the rest invalid. (I hated debating in HS, but that's the one thing I took away from it.)
Your follow-up post is much better in this regard. Though I think they're still fudging it slightly only mentioning in a footnote that Parisians only want tourists' cars to pay for being large. Parisians want their own cars to be as big as they fucking please; that proposal got scrapped right at the start of the process. I'm fairly sure a "3x parking charge for all non-residents cars, no matter the size" would probably pass too.
