I'm fine with a decently fair registration tax to offset the gas taxes, but the one in my state is the equivalent of 1,000 gallons of gas for the state gas taxes. If the car was a 35mpg hybrid that would be 35,000mi of equivalent driving. This is incredibly unfair.


35,000 mi of driving is not anywhere near out of the question if you're a daily commuter who takes road trips once in a while. If you're driving a truck or a non-hybrid, it's also a lot less mileage. It sounds like this is actually close to what you would be expected to use.


Just because a small percentage of drivers drive that much each year doesn’t make it a reasonable number for the general case.

It sounds like this is actually close to what you would be expected to use.

Not even close to what the average driver drives.


The average American driver gets about 25 mpg and drives about 15-20k miles. That's exactly in line with the tax rate here.


The average American car does not drive 20k miles. 12,500 is the average yearly mileage.

And it's an EV, a closer comparison should be something more like a hybrid. It's not a giant truck.


But it weighs as much as a giant truck


It weighs about as much as the smallest base model F150. Optioned out models and other trim levels easily hit 1,000lbs+ heavier.

Meanwhile that base model equivalent weight F150 gets about 24mpg and thus pays about half as much gas tax while doing the same amount of damage driving the average mileage. Further proving my point, I pay twice the state fuel tax for an equivalent weight pickup truck. Is that fair?

But also, isn't the whole point of the pickup truck to load it down? If all it's doing is carrying 1-4 people it's whole life, seems like a lot of waste. I'm told people buy trucks to actually load them down a lot and not just commute and get groceries? So while it's about the same weight dry and unloaded shouldn't it's weight really be quite a bit more in practice? Or are we all agreeing now trucks are just for commuting and getting groceries?


Seems unlikely.

55 miles/day, 365 days a year? Also, look at lease mileage limits.


Now you've moved the goal posts to about half of your original claim. And it's still not accurate (links have already been provided elsewhere in this thread). And the only thing I've owned in the last 30 years that gets 25 mpg is a camper van (and, no, that thing doesn't move anywhere near 15K miles/year).


It's far away from the average of around 12,000. Few cars drive 35,000mi.


> With that information, the British newspaper calculated that BEVs [battery electric vehicles] could expose roads to 2.24 times more damage than gas cars.

If that's true, then 12-15k miles in an EV would be equivalent to 27-33k miles in a gas car.. so "taxes equivalent to 35k miles" isn't far off.

Ref: https://www.autoevolution.com/news/bevs-could-also-damage-ro...


The average driver also doesn't get 35 mpg driving regularly. The average driver probably gets around 20 mpg, and that would make this distance about 15000 mi.


The kind of people choosing an EV wouldn't get a 20mpg car, it's an unfair comparison.


They also chose a car that's extremely heavy (by virtue of the battery), so they create more road wear per mile than the average American car. The point is that tax rate seems fair.


The ICE I would have picked otherwise is only 100kg lighter and gets 40mpg.


And you’d be paying gas tax


Far less than what I'm paying with the EV, which is my point!

If I owned an ev for 3 years, the tax means I save money.


This is a yearly tax. So that would be the same as 105,000mi in three years meanwhile the average car probably only drove ~37,500 in that time period.


The EV tax applies to people who a) casue a disproportionate amount of wear & tear on the roads vs ICE vehicles and b) are generally higher income in the state.

When you look at taxation from a "charge the people who use it" or the "the rich should pay more" perspective, this appears to address both.

Is the problem simply that you want to pay less taxes?


> casue a disproportionate amount of wear & tear on the roads vs ICE vehicles

If it was, it would be based on vehicle weight and distance driven. Where I am, at least, it's simply a tax on efficiency.


No, I just want to pay a fair amount of taxes. Honestly the gas taxes should be increased or we should move to a tax structure where it's mileage, weight, and emissions based.

Paying 3x the same taxes while having less externalities isn't fair.


As I've cited elsewhere on this thread:

> With that information, the British newspaper calculated that BEVs [battery electric vehicles] could expose roads to 2.24 times more damage than gas cars.

Ref: https://www.autoevolution.com/news/bevs-could-also-damage-ro...

If that's true, then 12-15k miles in an EV would be equivalent to 27-33k miles in a gas car in the externalities of road wear & tear.. so "taxes equivalent to 35k miles" is at most 25% higher in a "damage per mile equivalent" but could be as little as 6% using the averages.

If your actual mileage is over 15625/year, then you're paying less than the equivalent.

What's your annual mileage?


27 isn't 35 no matter how many times you say it is.

> If your actual mileage is over 15625/year, then you're paying less than the equivalent.

The average is less than that by a decent bit, so more than half of US cars are paying more even with your unproven, contorted math based on some estimates done once in the 70s and never really looked into closely again.

It's also assuming the difference in weight. The closest hybrid I would have bought instead is only like 100kg lighter than my EV. And it gets like 40mpg, better than 35mpg.

It would also mean semi trucks should pay like 20,000x more in registration fees. Does this make sense?

> What's your annual mileage?

Less than 15k on that car (like most people), so even with your assumed math it's overpaying.


Semi trucks pay huge amounts in gas taxes because they guzzle gas like nobody's business. It's only the EVs that aren't paying for their road wear in gas taxes.


20,000x more in taxes?


Realistically speaking, they probably do. Do you know how much fuel they use and miles they drive per year?


Average class 8 truck (>33,000lbs) burns under 11,000GGEa year, ratio is 1GGE=1.13gal of diesel. So somewhere under 12,500gal of diesel on average, but we'll use that to lean even more in the truck's favor.

https://afdc.energy.gov/data/10308

Are you suggesting the average car burns less than 1 gallon of gas a year?

A 20mpg car driving 12,500mi (the average ICE in the US) would use 625gal of gas. So more like 20x, maybe 40x if the per gallon tax of diesel is double. Pretty dang far off from 20,000x.

And they're doing way more miles while being massively heavier, meaning incredibly more harm on the road than whatever EV you're thinking.


GGE: Gasoline gallon equivalent

<https://en.wikipedia.org/wiki/Gasoline_gallon_equivalent>

(Most tractor-trailor rigs burn diesel rather than petrol.)


12-15k miles in a Ford SuperDuty is equivalent to how far in a gas Civic? I suspect that driver isn't being charged accordingly.


Registration fees are likely the same or close but when you factor in gas taxes (the original comparison here), the Ford is definitely paying more both based on fuel type and mpg.


More, sure. But not remotely proportional to the increased wear and tear from vehicle weight.


Possible. How far off is it?


Pretty far?

According to your link, an EV that is 700lb heavier => 2.24x damage

Civic: ~2900lb SuperDuty: ~5700-7600lb


What is the difference in taxes paid for an equivalent amount of damage?

I understand the point you're trying to make - and you may be right - but you're leaving out the math to demonstrate it.


Civic fuel economy is about 2x an unloaded SuperDuty, so the SuperDuty owner likely pays maybe a bit more than 2x in gas tax + registration.

+700lb (+25%) => 2.25x damage +2800lb (+100%) => ???x damage

Your story doesn't provide a formula, but seems obvious it is much, much greater than 2 - this isn't a linear relationship

And that's the very lightest SuperDuty model, unloaded.


Excellent, much more useful.

Not sure where you are but in Indiana, gas tax for unleaded is 36c while diesel is 62c so on a per-gallon basis, that's an additional +72% in taxes. Back of the envelope: Civic at 30mpg pays 1.2c/mile vs SuperDuty at 15mpg pays 4.13c/mile so the multiple is closer to 3.4 vs 2

So yes - assuming registration fees are comparable and mileage is comparable - the SuperDuty should pay more.


The lightest SuperDuty has a gas engine. Diesel SuperDuty fuel economy is a bit better, but the vehicle also weighs more and is likely to be carrying/pulling more. But regardless of whether the multiple is 2 or 3.4 or somewhere in between, it is a small fraction of the added road wear.

By the fourth power law, an unloaded diesel Superduty creates ~22x the road wear of a honda civic. Loaded can be 100x more.


You keep repeating it, but it's reductive at best and incorrect as a general assumption.


Is there another model you'd recommend to estimate/compare road wear and tear?


1:1 is at least as good a default assumption.


Based on numerous studies, we already know it's not 1:1 so why bother starting with a default assumption that we know is wrong?

Do you have an alternative analysis? I'd love to check it out.


> Based on numerous studies

I do agree the relationship probably isn't linear, but the fourth power rule doesn't necessarily have numerous studies confirming it. It was a small collection of studies on road wear the US highway administration did in the 1950s and pretty much everyone has just gone with that. Other studies have pointed to it being less than previously thought.

Throwing even more weight against your 12,000mi is really 35,000mi equivalence.


Thanks for the insight but my claim was never "12,000mi is really 35,000mi"

Regardless, it would be interesting to see the actual number worked through to see what the equivalent EV registration fee should be if road damage/maintenance is the sole factor.


> If the car was a 35mpg hybrid that would be 35,000mi of equivalent driving.

> that's true, then 12-15k miles in an EV would be equivalent to 27-33k miles in a gas car.. so "taxes equivalent to 35k miles" isn't far off

You absolutely did suggest me paying taxes for 12k miles is practically the same as ~35k miles, you said it several times. That it's not far off. How else am I supposed to read that? You were so sure of it you mentioned it many times.

> Regardless, it would be interesting to see the actual number worked through to see what the equivalent EV registration fee should be if road damage/maintenance is the sole factor.

Sure, but it's likely far less than what I'm paying. As mentioned elsewhere, a similar weight unloaded F-150 pays half the taxes. So I'm at least paying double for similar weight vehicles, and yet you tell me it's really only 6%. But sure, tell me again how I'm really just paying my fair share and 12 = 35.


> If that's true, then 12-15k miles in an EV would be equivalent to 27-33k miles in a gas car in the externalities of road wear & tear.. so "taxes equivalent to 35k miles" is at most 25% higher in a "damage per mile equivalent" but could be as little as 6% using the averages.

^ As you quoted, I used the formula to estimate 12k would be equivalent to 27k and said paying taxes equivalent to be 35k miles is "at most 25% higher", neither of which is "12 = 35". Using their approach, I calculated 35k to be equivalent to 15625 specifically, again, not 12k.

If the underlying approach is wrong, we should replace it with something better.

Alternatively, the OTHER reasoning of "the rich should pay more" still applies, so I assume that's a factor here. Hoping States charge rich people (or high income earners, if you prefer) less isn't likely to work right now.


> Alternatively, the OTHER reasoning of "the rich should pay more" still applies, so I assume that's a factor here.

Once again, your assumption is incorrect. That base model F-150 that pays half the taxes costs more than my EV. The registration fee doesn't factor in income or valuation at all. A $100k Hummer EV pays the same as a $15k used Bolt. Meanwhile that Hummer EV is going to do a hell of a lot more damage to the roads than the Bolt.

It probably has more to do with the government being in the pocket of oil interests and acts accordingly.


I don't agree with your base assumption here.
