Charge road use taxes by vehicle weight. Yes, electric cars are heavy, but so is the average American vehicle, because people seem to love their enormous trucks. If you have a Model 3 or a roadster, it’s actually lighter than the average.
According to U.S. Environmental Protection Agency, the average weight of a car is around 4094 pounds. A small car weighs around 2600 pounds, while a large car weighs around 4400 pounds.
- Tesla Model X Plaid - 5,390 pounds
- Tesla Model X Standard Range - 5,185 pounds
- Tesla Model S Plaid - 4,766 pounds
- Tesla Model S Long Range - 4,561 pounds
- Tesla Model Y Long Range & Performance - 4,416 pounds
- Tesla Model 3 Long Range & Performance - 4,065 pounds
- Tesla Model 3 Standard Range Plus - 3,582 pounds
- Tesla Roadster - 2,723 pounds
You’ve got it right, but let me expand with the power of mathematical modelling. The average vehicle is, for the last 20 years or so, pegged at 4000 lbs when doing road damage calculations. A Chevy bolt EV is around 3800 lbs, or smaller than average, while Tesla vehicles are like you said. The fourth power law is what is used to estimate road damage, and the take away point from that is that all vehicles in and around that 4000 lb range and nothing, notta, moot, compared to large trucks and shipping rigs.
As an example. Take the bolt EV at 3800 lbs, the F150 at 4200 lbs, and the F350 at 6764 lbs.
The bolt and f150 would have 1900lbs and 2100lbs per axle respectively. Applying the fourth power rule the F150 does (2100/1900)^4= 1.49 times the damage of a Bolt EV. Meanwhile the F350 does , (3382/1900)^4 = 10 times the road damage.
So then, is it true that the F150 and F350 will be made to pay 1.5 and 10 times the registration and fuel taxes of an EV like the Bolt? I have not yet seen this to be true. Now imagine how much damage a delivery van, or large shipping vehicle does.
The other part of this is environmental damage, are these states going to find a way to charge for carbon emissions proportionally from the gas vehicles? Of course not.
In Canada anyway fuel taxes go into general revenue, not to roads, that’s a whole different line of argument.
I’m curious and a nerd about this stuff. Why is road damage estimated using a fourth power law? What is the physical reasoning behind that?

TLDR: we experimented in the 50s and this is the model that fit.
With safety regulations, I thought smaller cars are around 2800-3000lbs now. A 7 year old (2016) Mazda 3 (compact car) is showing as 2900lbs. When you say small are you talking like the sub compact cars? Just trying to get an idea of what small means in this instance.
Compact sedans, and sedans overall are a dying breed. Car manufactures have largely replaced with with compact crossovers, or even worse egg shaped subcompact crossovers.
A new Mazda 3 weights 100-300 pounds more than that 2016. The Buick “code” subcompact egg weighs about the same 3300 pounds. Your more typical Ford explorer weighs 4300-5000 pounds. The escape is surprisingly light at 3300-3900 pounds.
Mazda is also an example of manufactures that try to keep things as light as possible to maintain handling. They also make the 2300 pound Miata.
Oh I’m aware they’re dying in America. I just wanted to see what small car was defined as because unless you get the Miata (which is one of the lightest cars out there) you’re getting up in the weight. Hell, I have a GR86 and it’s supposed to be a lightweight and great handling sports car and it’s 2800lbs empty.
