The Hyundai custom N mode… you can literally push a button and make your car more annoying.
You want it, you don’t need air travel.
In what way can air travel be said to be necessary? I am curious. How was this necessary air travel done before we had literally thousands and thousands of airlines in the air belching out the deisel exhaust? You want it, you don’t need it and no body else does either.
No one really needs fire.
Everyone living outside the tropics does.
Well, no one really needs to live outside the tropics.
American Football is demonstrably a worse sport than either of those, in terms of health outcomes for the players. I was being a little random. I think the cultural obsession with competition is a bizarre fetishism but that’s another thread, for sure.
Almost, yes. What couldn’t be grown and processed locally just wasn’t eaten. Sugar and salt would have been bought in; both were needed for preserving. My grandparents, on their farm in Wisconsin in the 1920’s through 1950’s, grew virtually everything they ate, and that was normal. They raised pigs, cattle, chickens, geese, they had an enormous vegetable garden and a big orchard.
In any town there would blacksmiths, wheelwrights, tanners, coopers, cobblers, rope makers, etc. Women sewed all the family clothes. This was not as long ago as you think. The total separation of consumers from what they consume is brand new in the history of the world.
Not everything; people have been engaging in long-distance trade for, probably, as long as we’ve been homo “sapiens” and possibly before. But a lot of it, yes.
I don’t think anybody’s suggesting that every village ought to be entirely self-sufficient. But there’s a whole long way between “make everything needed” and ‘have to drive half an hour or an hour each way at modern car speedfs to get to work each day, or to get basic groceries’.
And then, as has been pointed out, immediately wash their hands.
I think it’s probably more of an issue if people using the soap have been handling something greasy or sticky, because the pump itself would become unpleasant to touch, and if the grease or sticky stuff is food-related might start to stink and/or attract flies. Doesn’t really happen with bar soap, because you’re rinsing the outer layer off as you use it.
If the planet gets much hotter, people will need to, because the tropics will get too hot to live in.
(Yes, I know, that’s not the point you were trying to make.)
It’s interesting how much of this discussion has revolved around transport.
In an agrarian society whose economy revolved around everyone pretty much growing their own food (with the exceptions of stuff which was traded/bartered), the transport network was rudimentary – horse and cart level. Population growth and customs such as primogeniture put enormous pressure on that. If a farmer grew up and had X kids, either the eldest son would inherit the farm, or it would get parcelled out among the other sons. The latter obviously couldn’t continue for more than a generation or so. In the former scenario, what about the younger sons? If they couldn’t all find work nearby, they would have to move somewhere where they could. (I’m not ignoring the daughters – they either got married off, became governesses or teachers, or remained in the family home to look after the parents. Tough on them. A few exceptional women would have founded businesses, etc. Props to them.)
As people fanned out further from their birth place, and the economy started to resemble a modern one based on trade, there was more pressure to develop roads and better vehicles. Currencies and uniform systems of measurement were yet to be invented. (Before the development of the metric system, France had thousands of measurement systems. I am old enough to remember rods, poles and perches, and imperial currency.) Again the need to facilitate trade motivated these things.
We are really talking about the sociology of technology, something one can’t do more than make a crude sketch of, like the above, in this forum. But any advanced economy depends on a transport system of similar sophistication. See how much longer a trip takes you when a road is half (or entirely) closed.
If you could travel back in time, and see first-hand the sort of mess and smell that horses made in cities, I think you would change your mind about cars pretty fast.
Cars are a major improvement, in multiple respects, over what existed before.
I put stickers on the various cameras [laptop, tablet, cell phone] that I remove if I need to use the camera. Just did a telehealth zoom with my oncologist because when I did the ritual pre-appointment covid test I popped positive, so I opted to not go into an office full of immune compromised people and spread the ‘joy’.
Would it be impossible to sticker over the TV or other appliance cameras? [I also used to chop wires to get plugs to go into the mic jack so it diverted mic to a nonfunctioning plug so it wouldn’t take in audio signals]
Scenario: You need a heart transplant to live. A compatible donor heart has just become available, but it’s in San Francisco and you’re in Tallahassee.

There I’ve gotten more answers ready for debate.
I’m not sure I want to meet the guy who invented cancer.
There’s no reason at all to go back to horses in cities, when there are already a wide variety of better options in successful use, from bicycles to rail. Most of the horses in cities were moving freight of one sort or another, or were transporting wealthier people who had hired them. Relatively few were directly analogous to how cars are used now, as purely private conveyances. This is not a cogent argument in favor of cars.
Believe it or not, I couldn’t find the camera. And I don’t recall if it also had a microphone. The truth is, the disclosure on the particular TV I bought was probably generic and the particular one I bought may not have had a camera. But the terms and agreements said it could have a camera and that it would spy on me, and that was enough for me to return it. Perhaps using boilerplate language in their user agreement cost Samsung a sale.
I thought something similar but yours is funnier. 
That doesn’t mean there can’t be improvements over cars; at least, in their current form.
Nor does it mean that we can’t consciously start designing to allow living without one. Many municipalities are already consciously designing for pedestrian and bicycle travel, as well as for better public transport.
We can’t undo the route we’ve taken to get here. But that doesn’t mean we have to keep blindly heading in the same direction.
All these wealthy people in London?
We’ll call them freight 
I think that would be a horse bus!
My points stand though. Working class city people in the era of horses probably mostly walked or rode bicycles.
