This came up in another thread and while it's sort-of true, it's not really. Passenger vehicles of ANY size do almost no damage to a road in comparison to semi-trucks and delivery trucks. A 3/4-ton pickup vs your toyota camry is MAYBE a 2x increase in damage to the road. The average semi vs. that same 3/4-ton pickup is a 2500x increase in damage to the road on the low end (some studies claim as high as 10,000x).
Unless you're planning on eliminating the trucking industry, shrinking cars isn't reducing the wear on our roads in any meaningful way.

- shiftpgdn 3y agoThis should be obvious to anyone with eyes too. Go look at a neighborhood with no or low through traffic and extremely old roads are in good condition. Meanwhile a nearby through-fare, unless constantly repaired and patched, will be falling apart.
- giantg2 3y agoEven the low traffic roads in freeze-thaw regions need constant repair. So it's not all weight related. Weight is a factor that really only matters once you start looking at commercial size vehicles.
- KeplerBoy 3y agoAlso look at your local bus terminals. That asphalt is damaged beyond belief, even though it sees next to no traffic. A few dozen buses a day braking and accelerating on the same patch of street over and over will wreck it.
- warrenm 3y agoThanks, asphalt! Yeah - it happens to concrete, too ...but it takes way longer
- Fatnino 3y agoThere's a ghost town in california called new idria. Obviously, very little traffic on the road leading to it. The pavement surface is probably 50 years old and in reasonable shape except for certain areas that make you wish you brought a 4x4
- vel0city 3y agoIn my area its immediately obvious which lanes and roads have bus routes. A three-lane each way road will have two nearly pristine lanes and one completely beat to hell. Guess which one the bus takes.
- chrismcb 3y agoI would expect a neighborhood, even where everyone owns a semi to have significantly less wear than a thorough-faire that sees a lot of traffic. But even that didn't tell you everything. A good quality asphalt will out last a poor one pretty much no matter the conditions. We have a stretch of road near us that is always in bad shape, when another stretch, seeing the exact same traffic is in good condition.
- nwallin 3y ago> A 3/4-ton pickup vs your toyota camry is MAYBE a 2x increase in damage to the road. Your source states that relative road damage between two vehicles is the forth power of the ratio of their weights. The base curb weight of a Ford F-150 is in the vicinity of 4,600lbs. The base curbs weight of a Toyota Camry is in the vicinity of 3,500lbs. So the damage ratio is (46/35)^4 = ~3. The Toyota Camry used to be a small car, but it isn't anymore. The base curb weight of a Ford Fiesta is in the vicinity of 2,500lbs. So the damage ratio between a Toyota Camry and a Ford Fiesta is (35/25)^4 = ~3.8, and between a Ford F-150 and a Ford Fiesta is (46/25)^4 = ~11.5. So a Toyota Camry, being somewhat of a behemoth, should be paying on the order of 3.8x the amount of road tax as a Ford Fiesta.
- ProfessorLayton 3y agoEven so, unless we're charging the average semi truck 2500x more road tax, and vehicles of that weigh class which cause the overwhelming majority of wear, the roads will continue to be as abysmal as they currently are.
- taeric 3y agoI confess I assume that we do charge trucks an absurdly larger amount of money? Is why they have weigh stations between states?
- tw04 3y agoThat depends on what you consider "absurdly larger" - the fee is between $1,000-$2,000 depending on the state. In some states that's not much more than you'd be paying for a nice luxury car or large SUV. https://www.truckinfo.net/research/license-costs-by-state https://www.truckinfo.net/research/license-costs-by-state
- taeric 3y agoI confess I had a mistaken thought that weigh stations were akin to toll booths. That is, that fees were levied based on the weight. I can think of several problems with that thought, taking it longer, of course. :(
- joeman1000 3y agoYes, this is true. I’m a transport engineer and can confirm that roads are designed for a truck’s weight and cars hardly register in terms of damage.
