It’s not meant to be a single digit multiple of the UK tax, I don’t know where you’re getting that from. The things which the article mentions as being single digit multiples are:
In 13 countries, acquisition taxes for such an SUV are more than three times higher than the UK’s
£3,200 in the UK, but the sale would incur taxes of £66,600 in France – driving UK SUV sales to four times the level in France.
And the headline figure is “up to 20 times”, which roughly matches the £66k.
I’d love to see a “Get rid of the petitions system, its sole purpose is to make people feel they have been listened to while you continue to ignore them” petition get enough votes to be debated.
