Do they? I mean, trucks are hardly gas efficient, and aren't most roads maintained (supposedly) via gas taxes?
The question, I suppose, is how much harder they are on the roads relative to their fuel efficiency.
- lsy 9y agoFuel efficiency decreases generally relative to the surface area of the front of the vehicle, where road damage increases with the mass of the vehicle. So a long, heavy vehicle like a truck is indeed harder on the road relative to their fuel efficiency.
- andechs 9y ago> road damage increases with the mass Road damage actually increases proportional to mass^4 - trucks cause exponentially more damage than cars. https://streets.mn/2016/07/07/chart-of-the-day-vehicle-weight-vs-road-damage-levels/ https://streets.mn/2016/07/07/chart-of-the-day-vehicle-weigh...

- emodendroket 9y agoPerhaps on a related note, our roads are in embarrassing condition.
- hfdgiutdryg 9y agoaren't most roads maintained (supposedly) via gas taxes? The last time I looked into this, studies put it at something like 50% - 80% of costs paid for by fuel taxes. It's hard to come up with a straight figure because of so many levels of intermingled tax funds.
