Maybe offtopic but a surprising bit of extra information regarding wear and vehicles: Road wear scales with the fourth power of axle load, so heavier vehicles do much more damage than one might expect. Take a 40t truck with 5 axles vs. a small car with a weight of 1t and two axles (e.g. VW Polo, maybe an older VW Golf might only weigh 1t as well): (8t axle load / 0.5t axle load) = 16^4, i.e. the truck puts 2^16 (6553…

I remember a civil engineer telling me once that if highways only had cars on them they would last 100 years between repavings.

I don't doubt it, we have a local road here that has been fine, but this year they decided to drive a lot of truck loads of snow to save a skiing event from another city up that road and now it's completely destroyed and it needs new pavement and possibly new foundations in several places.

Trucks should really only be a last resort for the last mile to the store and the rest should be sent by rail or boat and loaded onto trucks if necessary.

They also have huge externalities when it comes to damage to other cars, when my car is hit by rocks on the road it is always coming from a truck.

In France the rubber tyre lobby is so strong, the got them on subway cars. No joke: https://en.wikipedia.org/wiki/Rubber-tyred_metro

The subway has tires for technical reasons. Stations in the Paris subway are close enough that better acceleration times have a significant impact on travel time and peak-hour capacity.

If they were willing to retool, you’d think they’d just go with a maglev monorail design. Those have the capacity for the instantaneous acceleration of a railgun.

Having lived next to a freeway, I found everything in my apartment covered with a sticky black dust that took hours to remove. I found embedded on books and other items years later. So, I think this has been true for a long time.

What I didn’t find mentioned is these emissions were more or less localized to a small distance from the road. For example when I moved it went away. That said I’m sure it’s a nightmare for the watershed.

That would be a pretty rough ride. I wouldn't want to be a straphanger on one of those. The turns would be uncomfortable as well in a railgun railway car.

Worse for what? For the humans nearby? For climate change? It would be nice if such articles stated their premises.

Without defining the central term of its central thesis (let alone citing any sources) it's generous to even call this an article.

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.

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

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.

This fact is especially pertinent when folks with their F150s demand that road bikes be taxed equally to use bike lanes.

Taxing by fourth power axel weight per mile sounds good $10 for a bike doing 1000 miles a year, so 1 cent a mile. Gross axel weight about 100lb. So axel weight of 1000lb would be $100 a mile. F150 at 2500lb would be $4,000 a mile. I suggest putting the first year on the sale price, so that $200 bike costs $210, and the $60k f150 costs $60 million.

Yep that's usually the response I give to folks in my neighborhood FB group. They are conspicuously absent to the conversation after that.

It would also be useless, the stations are so dense that you would barely increase the average speed.

The claims here seem dubious. They tested one type of brand new tire. Then they conclude that "high-quality" tires are somehow better without providing any evidence to support that claim. While tires may very well be a source of pollution I have to wonder where the money for the work came from.

Shitty tires start with the same tread depth, but wear out in 25-35k miles. High quality tires usually go 50-60k.

Tread wear isn't a measure of quality, it's a measure of the how much 'grip' a tire is designed to have. High performance tires are softer to grip better, but wear out much much faster than tires designed for higher mileage. The higher mileage tires have worse performance characteristics - greater stopping distance, etc.

At Michelin, we're more than just Green guides, we put our tires on the subway cars and encourage protesters to use ours for all their tire fire needs.

Maybe the study should also take into account this use of tyres.
