Yes, but I think OPs point is if you're taxing vehicles according to their contribution to road damage, then cars should efficiently be taxed at 0 (I don't know I'd that is true, but it seems to be the point their making). If heavy goods are 100% of the damage, they should cover 100% of the tax. Now that said, I'm not convinced they are actually 100% of the damage. I've seen many residential streets in need of repair that essentially never see heavy vehicle traffic. And I'm also not certain that taxes should be based on cost added vs value provided - but it's a reasonable discussion to have. But again this seems short sighted. Electric vehicles (vs ICE) remove a ton of negative externalities from society. And while they do bring others (in how many of their materials are sourced) they are a big net positive. Don't disincentivise them because of a change in fuel tax revenue.
