Uh, you could technically have this in an apartment building, depending on the type of storage / parking available. There’s gated parking places in some apartments nearby me and if this fit through the door, you could technically keep it in the bikeshed, I guess.

But a horse? Nah, a horse needs shelter from the weather, food, cleaning, medical attention. Also they’re brittle af. If a horse breaks its leg, it’s still more or less the only thing to do to put it down. Perhaps if you’re obscenely wealthy you could try and have all sorts physical therapy devices and just supports designed for them and have them held up each night while sleeping or something but I still don’t know whether it’s even possible.

Oh, yeah, apparently they can survive minor breaks with modern veterinary care, but above the knee or serious, like a compound fracture and the main go-to is still euthanasia.

Anyway yeah horses are expensive af and take a lot of caring. Whatever this thing costs the cost of use should be waaaay cheaper than a horse. And horses aren’t cheap to get either.
