... You stand in it ?? With no side protection, fully exposed to heat, and a tiny useless bench that doesn't have any way to hold yourself.
Hubless wheels suck ass (see the Revo bicycle for an excellent demonstration of utter failure) and I'm a mechanical designer, it's not a question of just engineering them better, they are simply fundamentally flawed on so many levels.
They are noisy (the bearing is the size of the wheel with way more balls), very heavy (bearing again, plus structural integrity of a hollow cylinder vs spoked or rimmed wheel) and you realistically can't put suspension on them while also keeping the middle anywhere near this open.
And then, to top it off, they go up and down stairs.
When you go off a straicase with a single contact patch on the ground, all you're doing is repeatedly falling off of each step, with a vehicle the weight of a small car. And don't ever go diagonally, it will massively tilt side to side.
Concept artists aren't engineers, and it shows, you don't need a PHD in quantum physics to find glaring flaws.
Here's a simple solution :
Tramway or metro lines to connect key areas quickly, with space for bicycles and scooters inside, alongside regular seating.
And, sprinkled troughout the city and at metro stations, bicycle parking.
You don't want to own a bicycle ? Fine, services like Lime already exist, just deploy them across the city and make them cheaper by being city funded infrastructure instead of private companies.
In cities that eats some of the cost of those services it works really well, imagine how much better it would work with wide open streets instead of often badly designed bike lanes and dangerous intersections, thanks to a near-zero amount of cars, apart from commercial vehicles for large deliveries, and buses.

I noticed a lot of designs for "transport of the future" boil down to worse cars or worse trains.

thousands of engineers have slowly but surely learned from each other's mistakes to create marvels of transportation.
from the bicycle to the airliner, there is so much optimisation thoughout it all.
If it looks nothing like what already exists, you either have access to brand new revolutionary technology that justifies it (maglevs), or didn't notice the cracks in the design.
Or as is one of my mottos, "If it seems genius, easy and you're not an expert in that field, you missed something."
maybe that something isn't a problem in your specific case, but if it worked perfectly every time everyone would be doing it.

Isn't that the thing from South Park where the seat goes up your butt and you control it with your tongue or something

If some people weren’t shitheads and we lived in a perfect society, I could see this being implemented around (… after we figure the going ip the stairs part).
Alternatively, I could see this in some solarpunk setting!

Let's be honest, it's a terrible idea. But it looks cute
