> Road wear scales with the fourth power of axle load, so heavier vehicles do much more damage than one might expect.

Yes. Electric vehicles with their heavy batteries also make things worse.

Except no. The heaviest Tesla Model 3 weighs 4,100 lbs. The heaviest Ford F-150 (the most popular vehicle in the US) weighs 5,600 lbs.

Right but people buying F-150s are not buying Teslas. The use case is quite different. My Subaru Outback (a rather large car in comparison to the Tesla) is 3,600 lbs. But I doubt the increase in weight is a huge factor in environmental concerns.

But compared to freight trucks, the F-150, the EV, and the Outback are all inconsequential.

Have you been to a Texas city? They're full of F-150s driving around a single person and an empty bed on paved roads.

Sure, farmers and contractors use trucks as trucks, but thousands of people use them as commuter cars. Most pickup trucks are used as trucks once in a blue moon.

If you want to make this argument you should account for the weight of a loaded F150

A Toyota Camry weights 3600lbs, so it's not like EVs are extraordinary heavy either. Additionally, 15 gallons of gas is about 100lbs.

15 gallons of gas is 90 pounds.

Isn’t Model S closer in size to Camry? A Corolla is closer to model 3 size and more like 2900lbs. The P90D with less range than that 100lbs of gas Camry is 5000lbs.

Interior dimensions are all very similar. Exterior, the Model S is the largest, followed by the Camry, Model 3 then distantly the Corolla.

Interior volume of Camry is 115 cu ft (27lbs per interior cubic foot without gas, some marginal amount more with the same amount of gas as P90D's range, which only takes around 60-80lbs of gas or so).

Model S P90D is 120 cu ft (41lbs per interior cubic foot).

Does that take into account cargo space?

You are comparing an F150 with a Tesla 3?
Re:Pollution from tire wear is worse than exhaust emissions? by fjeifisjf on Sunday March 08, 2020 @11:53AM (#22518639)
Not really. EVs are slightly heavy. Loaded trucks are much heavier.

Side point: EVs do most of their breaking via regeneration, so much less brake dust emission.

The battery is heavy but the powertrain is much lighter. You can make light electric vehicles, look at the i3 for example.
