Like everything Hidalgo does this is performance art pretending to be a solution.

If you read the fine print (not mentioned in this article I’ll go find a French article and edit it in) the problem here is it DOESN’T affect residents, only those from outside Paris.

What does that mean ? The millionaires in the 6th arrondissement can keep their Porsche Cayennes, Lamborghini Urus’ and Bentley Bentaygas free of charge but the electrician or builder coming in from the banlieues and peripherique in his Toyota Hilux will pay an extra tax.

The weight tax also creates challenges for a tradie to swap his ICE VW transporter for an EV equivalent.

All is not as it seems. If she makes it a tax on SUVs in Paris regardless of where you live (more like the London ULEV setup in the sense that it applies to everyone regardless of residence) then it may do some good

Edit 1 it is in the guardian article

"The prices will apply to vehicles weighing more than 1.6 tonnes with a combustion engine or hybrid vehicles, and more than 2 tonnes for electric vehicles. The move will not apply to Paris residents’ parking. "

Edit 2 a little more pointed

https://www.lemonde.fr/en/france/article/2023/11/14/paris-will-have-residents-vote-on-increasing-parking-fees-for-heavy-suvs_6255482_7.html

"If the vote goes in favor of the fee hike, it would not concern SUV owners with residential parking permits issued by the city. "
