Earlier quoted context omitted.
It also adds to the price of food that gets transported from one place to another, and, as such, acts as a regressive tax on people who pay the biggest part of their income on their basic needs (like food). That's one of the main reasons why I don't get the "death to cars!" movement and why I regard it as mostly middle-class privileged discourse: no cars means fewer or worst roads, means food being a lot more expensi…
A truck can carry 10 or 20 times more cargo than a car. The truck toll is not 20x more. The movement to reduce car use is about replacing them with better alternatives such as efficient local public transport and high speed rail, not going back to travelling on horseback.
Yes, that was my exact point. The car owners (of which I'm one) subsidise cheaper food for many not car-owners (many of them, presumably, poorer people) by paying more expensive road tolls relative to our vehicles' sizes. And that's good.
Make road toll for trucks commensurate to the real wear they're adding to the roads then you're increasing the price of food (by increasing the cost of transporting said food), hence you're making it harder for poorer people.
