Trucks basically do all of the damage. Generally they can have 16,000 lbs per axle. With 5 passengers, a Model X weighs 6000 lbs and has 2 axles. 16000/3000=2.66. 5.33^4=807, plus the truck has 2.5x as many axles, so the semi is doing 2017x as much damage as the car. Even in residential areas, package delivery trucks are always driving around, and they often have about 15000 lbs/axle, so they're doing about 625x the damage of a Tesla X. Road damage due to passenger vehicles is just not significant, even if they're heavy for a passenger vehicle.
