Ohh, so “pavement” meaning a sealed road surface?

In my head I’m trying to figure out what the footpath (U.S. “sidewalk”) a.k.a. U.K. pavement fits in with the jibe.

Apart from the pleasant one on the left, they’re all the worst. The 4th from the right is almost good, but then you notice the creepy-as-fuck centre tine-gap length.

They’re a little pricey I suppose, but judging by a few minutes comparing gumtree listings for hatchback cars and cargo bikes:

< 20% the cost of a hatchback in analogous condition/age/fanciness.

I suppose it’s likely.

Until then, keep riding. Cycling releases an order of magnitude less rubber dust than driving, and is distributed approximately according to population density on local roads/paths, not concentrated on traffic sewers/freeways.

DV-55521?

As per the quote below, a car loses about 0.08g of tread per km.

Compared to a car, a bike tyre is about the same diameter, 10% of the width (~20mm), 28% usable tread depth (~2mm), has 50% less wheels, and can travel 10% the distance (~10000km).

This suggests a (very approximate) tread loss of 0.08 * 10% * 28% * 50% / 10% = ~ 0.01g per km for bicycles.

For replacing longer car journeys less typically travelled by bicycle, rail transport is the best solution and removes the issue of tyre wear.

Quoting [deleted] in r/theydidthemath:

Using the same assumptions as above (215/60R16 tires, 7mm of tread loss over 100,000 km), I estimate the loss of tread by volume from each tire as follows:

Cylinder with a diameter of 664 mm and a height of 215 mm has a volume of 74,412 cm3. Cylinder with a diameter of 664-(2x7)=650 mm and a height of 215 mm has a volume of 71,307 cm3. The volume difference between a new and worn out tire is 3105 cm3.

Typical land to sea ratio of tires is 60-70% land, depending on the type of tire. If we go with an about average value of close to 65% tread, we get the lost rubber volume of about 2000 cm3 or 2,000,000 mm3 over a single tires lifespan.

Each revolution of a tire loses about 0,04 mm3 of tread, which, according to Wolfram Alpha, is a bit less than the volume of a medium grain of sand.

If we look at the entire car with 4 tires over a kilometer of road, we get 80 mm3 or about 0,08 grams of tread lost per car per kilometer.

BPA is found in polycarbonate plastics (acrylic) […]

Polycarbonate (BPA monomer) is a very different polymer to acrylic/PMMA (methyl methacrylate monomer).

Of course they would.

Yet for others it can make it way worse: https://en.wikipedia.org/wiki/Sexual_headache

Sounds like you have too few geese/sheep, that’s all. 😆

Nice.

Amendments to anti-terrorism legislation incoming in 3… 2… 1…

Excerpt from article:

“We all play a role in keeping our roads safe and Crime Stoppers Victoria is offering vulnerable pedestrians the tools they need to use our roads safely,” she [Crime Stoppers Victoria Chief Executive Stella Smith] said.

“We have seen 175 pedestrians killed on our roads over the last five years, and a significant number of those have been in 60 km/h zones.

“We hope with more education and awareness we can reduce the number of injuries and most importantly, deaths on our roads.”

As part of the campaign, Crime Stoppers Victoria will hit the streets to actively engage with high-risk pedestrians to educate them on how they can help keep our roads incident-free.

I guess that means police will be out in force handing out fines to pedestrians and cyclists. “Job done!”
