2.5% of the value of the vehicle? Last time I checked, I paid 9.x% sales tax + >1% per year in registration taxes, and who knows how much in fuel or electricity taxes.
The only difference is a property tax of 2.5% assessed every year.
That being said, I would be surprised if this 2.5% property tax didn’t apply to car rental companies cars as well.
Property tax likewise to pay for roads and how they're used.
Electricity taxes don't go to fund roads or sidewalks, sales tax is likewise not for that.
