Haha, I totally get what you mean. It would be pretty funny to imagine a world without motor vehicles. Our great grandfathers managed just fine without cars because they had other ways to get around. But nowadays, we're so used to vehicles that it would be chaotic if they were suddenly gone. People would have to start trekking long distances like they used to.

But you know what? I think it could actually be a good thing for our health. Without cars, more people would have to engage in physical exercise, which could lead to better health and longer lives. Humans are pretty good at adapting to changes, so I'm sure we'd adjust to the new situation. In fact, in my country, when the fuel prices went up like crazy, many people started trekking short distances instead of driving.

And you're right, we could always go back to using animals like horses, oxen, or camels for transportation. In the past, nomadic people relied on these animals to carry loads and transport them from place to place. So if we needed to, we could definitely enlist their help again. After all, humans have a way of reverting to old ways of life when the new ones don't work out.

So yeah, if motor vehicles were banned, people would just adjust their lives to the new situation.
