I think increasing the payroll tax is a mistake. People who don’t own a car should actually be rewarded because they pollute far less, they don’t disable workers, they don’t require traffic police, they don’t emit CO2…
I would replace the payroll tax with a weight tax on huge SUVs.
Even that’s not fair since efficiency isn’t the same thing as road usage. And one of the reasons gas taxes cover so little of the cost of roads is efficiency improvements over the last few decades.
Even before you take EVs into account, taxing by weight and mileage is more fair.
Then when you do take EVs into account, how do you adjust for usage, for road damage, and for your choice of vehicles? Is it fair to charge the same for a monstrous Hummer EV as for a Peugeot city car? Is it fair to pay the same for your Tesla driving 10k/year as for an ICE BMW of the same weight driving 30k/year? Taxing by weight and mileage is more fair for everyone
