Obviously parent post is not making the point you're trying to argue, only making the point that the measurement is flawed. If you are going to address their argument do it in good faith and address the strongest point. This isn't reddit

Thankyou. I think I will quote your last two lines frequently.

> Nobody is going to stop driving. Car tires are the largest source of microplastics. many already have, bicycles and public transport ftw

There's realistically fewer than twenty metro areas in the US where the majority of commuters could rely solely on biking and public transit for everything. Twenty might be generous, even.

Since the pandemic passenger car miles, airline miles are back at pre-pandemic levels.

Transit use is at 80% of pre-pandemic levels.

Farebox recovery ratios have consequently become even worse.

The new US government is also presumably not going to fund much transit expansion.

It'd be interesting to see if more people work from home on a given day than use mass transit to get to work.

It's also pretty similar in Australia at least and probably in more places around the world.

Doesn’t work. It’s in the rainwater. No rainwater on earth is safe to drink. https://www.bbc.com/news/science-environment-62391069

Does osmosis remove? Is it in all groundwater? Because I have a well. A deep one. And an osmosis system.

Do you consume drinks? Meat? Produce? All these things are chock full of their own micro plastics. It's unavoidable. We can probably reduce contamination but our children's children's children won't be free of it, not until organisms evolve to efficiently eat it. Then we'll have whole other sets of problems.

I'm not sure why you're being down voted for suggesting a practical and fact based solution. The USA is, regrettably, not making a pivot towards public transportation anytime in the near future. So, lighter cars are one way to address this issue. You didn't expound upon your point about the unintended consequences of CAFE standards but they're very real. Instead of making smaller and more efficient sedans per the gui…

Los Angeles would be very difficult to transition at this point, it’s just too low density. It was better 100 years ago than it is now.

I find it interesting that at a certain time in Los Angeles, a segment of society could afford a craftsman cottage house, but not afford an automobile. This was the prime era of the Pacific Electric streetcar suburb, say around 1890-1920. Today, obviously, anyone who can afford a house anywhere in the country can afford an automobile.

The end of the Pacific Electric system was not a conspiracy theory by tire companies or anything like that; the price of the cars dropped and that's what consumers preferred, i.m.o.

My understanding is the best thing you can be doing along with reducing exposure is regular blood donation

Interesting. My father has received a ton of donor blood over the past few years. Once he's gone I'll be donating regularly. My father's alive because dozens of people donated. To anyone here that has made a deposit to the blood bank: we thank you.

blood bank CEO thanks you too because the make millions selling your blood

And we need more lightweight cars , not heavier, since tire wear is proportional to vehicle weight to the fourth power. Ironically, CAFE regulations and EV incentives both did the opposite

You’re right, but the thing that leads us to lighter EVs is solid state batteries.

Hope you never have to drive to the grocery store

Hope you never have to haul a family of 4 worth of groceries on a bus.

I do on a bike or walking weekly, it's not that crazy.

In a prewar US mid sized city, the density supports multiple grocery stores I can reach in about the same time as driving and finding parking.

There is a positive spin on this: the majority of Americans already live in or near dense urban centers. If we had solid public transportation only within these centers and to adjacent suburbs we would eliminate most car trips. That's bot much physical area to cover.
