Australia’s roads are full of giant cars, and everyone pays the price. What can be done?
(theconversation.com)
People are surprisingly unkeen on tracking in their car. So kilometers driven wouldn't work.
I'd say just go with a fee based on the weight of the vehicle, exponential of course. We need fewer heavy cars, fewer kilometers driven will be a side effect. And as a bonus effect maybe I'd be able to buy an EV without a range that's 8 times what I actually need.
