Because trams and busses can't fulfill every need. Certain point to point transportation options still need to exist, we just need to make them as efficient as possible.

And as I mentioned in another comment, ~~turns out busses aren't really as efficient as I thought they were. Fully packed small cars are way more efficient~~.

Edit: Changed my mind. See previous comment.

Doesn't Lyft work sorta like that? Idk, it doesn't operate in my country, but from what I've seen online, it's several strangers sharing one ride.

But after giving it more thought, I tend to agree with you on this. Except... After posting my comment I got curious and decided to calculate the efficiency of cars vs busses. I always assumed that they were way more efficient than cars (cause lugging around 2 tons of steel just to move 1 or a couple 70kg hairlines apes is stupid). But it turns out that busses only win if we compare it to cars with only one passengers. So basically, at half load, both are about equally efficient (about 10%). And on average a bus is only half full. Turns out, busses are really heavy... there's of course the density, and busses win if you give each passenger their own car, ~~but if we pack cars fully, they will be significantly more efficient~~. Not to mention if you use smaller European cars that carry basically their own weight in passengers.

So my conclusion is, to maximize efficiency in the future we should try to implement a system of highly packed smaller sized transportation devices.

Edit: I did some more calculations and now disagree with my own conclusion. Busses still win even when cars are reasonable utilized, not to mention the usual utilization, which is 1.2 passengers.

More details in this comment.

Thank you, that is a very interesting insight. But besides sharing cars in parallel (multiple passengers at once) there can also be sequential sharing, which is, I understand, a regular taxi without a driver. But I think that high availability of cars like that, which are cheap, would still reduce the amount of car owners, and consequently increase public transportation utilization.

Things being close together isn't really an issue here because it's just meant to visualize the volume. They are not trying to paint a realistic scenario, I don't think.

While I'm a strong proponent of reducing and possibly eliminating car use, this image is disingenuous. They neatly packed 69 (nice) people into a medium bus, sure. But when showing cars, it's almost 1 persons per car (I counted 15 cars in a row and there are 4 rows, so 60 cars). You can definitely use cars more efficiently than that.

Assuming that actually autonomous self-driving cars exist, they could be extremely efficient. Especially if you treat them like ride sharing taxis. In other words, a lot of people could share the same car and that would reduce the amount of owned cars. They also never waste space being parked. So I can see how when we make a real self-driving car, it can potentially reduce traffic. Especially for all those cases where public transportation doesn't work.

And what the heck is a "connected car"?

But the meme is specifically about historical events, not modern day. And you also need to take into account that with the case of "top 1%", they often still pass on the family business to their children, even in modern days.

I just didn't want to make it bulky, so tried to bring in the core statement. My thought was that for more details, the Wikipedia link is right there.

FYI, you can disable the pop-up in settings.

Back then, pretty much everyone had. If your dad is a shit shoveler, then you're also a shit shoveler. Cause unless you find someone else to let you be their apprentice, your parents are the only ones who are gonna pass on any knowledge of a trade. Plus, your dad already got the shovel and the cart, and that's an investment!

It's ok, from all the downvotes and lack of genuine answers I already understood that asking questions here isn't encouraged and I should just treat this as a religion.

But if anybody eventually decides to sincerely answer my question, I'm still interested in expanding my knowledge.

Idk about "so many" other instances, but this post is clickbait. Company just hired 2 cosplayers for entertainment and didn't claim they were robots. It's no different from what Musk did for his robot reveal.

Nobody was busted, this is a clickbait post. Even the article just says they hired 2 cosplayers as entertainers, company never pretended that they were robots.
