When it’s easier and (value of time) cheaper, why not?

You seem to have different issues than the person I'm replying to. Maybe your situation is different. If you nearest grocery store is 45 minutes away by walking maybe your situation requires a different solution than someone who has expressed interest to walk but stated that they might buy too many groceries to walk that home.

Nope. A car is convenient (the comment I was replying too) in both situations!

Weird, eh?

I find it convenient to walk to my grocery store. It's inconvenient to have too many groceries regardless of my conveyance home.

Too many groceries to conveniently carry by hand in one go != too many. For some of us, anyway.

Yes, because we're a wealthy and productive society and the fruits of human progress in the past 300 years have allowed us to build a civilization where nearly everyone can afford to use a multi-ton machine of nearly incomprehensible complexity and sophistication to carry them around, instead of pushing a cart like a peasant 5,000 years ago did.

Check out eg https://youtu.be/hmk5cxpAfcw where he’s flying by all the cars stuck in traffic on his human-powered peasant wheels.

Auto companies lobbied governments and put out propaganda to get cities to rip out street cars and rail in the early 1900s. They did this to sell more cars, so this is what we get.

If you want to ban cars from New York City, that's fine with me. Do you realize that NYC makes up 0.008% of the land area in the United States?

Your young and fit rollerblade dude doesn’t seem to be carrying much in the way of groceries.

What about the mother of three with a disability? Should she push a cart to the grocery store?

Why can't the majority of the people walk to a store and the rest can be serviced by a smaller truck?

Yes we can afford this now. In the context of "Tire Dust Makes Up the Majority of Ocean Microplastics" how long can we afford this? Just like dumping Freon, and CO2 into the atmosphere have long term consequences that require our society to change, how long can we go aerosolizing rubber?

I wonder how hard it would be to capture this with some kind of aero device in the wheel wells of vehicles. Given what F1 teams can do with aero, it doesn’t seem like a huge stretch to be able to suck up these particles at the source and pass them through a filter bag like a household vacuum or something.

That's a fascinating idea. I hope someone (you?) pursues it.

I think the issue is the particles are from the friction of the road and to effectively collect the particles it would drastically reduce tire clearance, not an issue for F1, but for the consumer market tire clearance is important, for some reason.

Governments have paid very little attention to this problem to date. It seems like regulation on chemical composition of tires might be warranted. I don't have a problem with that.

Unfortunately we have been pushing the costs onto everybody else: as evidenced by climate change and micro plastics. And now the bill is starting to come due.

I have a wheeled shopping cart thing (not sure what to really call it, but it’s the standard one). I can only fit some milk and a few things in there, it is no where near as capable as my car. I still use it, since I don’t like driving to the store (we live near 3 big grocery stores, and a soon to be closed city target), and it’s useful for getting snacks to school when it’s my turn, but I don’t see it as a car replacement.
