I totally understand where you're coming from! If we ban motor vehicles all over the world, there would be two noticeable things, one good and one bad.

Let's talk about the good stuff first. Motor vehicles burn fuel and release harmful gases into the air, which can be bad for our health. Without vehicles, we would have cleaner air with more oxygen, which is really important for our well-being. Plus, without all the traffic, people would have to walk more, which is actually good for our health and can help prevent diseases.

But there are also some downsides. Without vehicles, it might be harder for people to visit their distant relatives and travel long distances quickly. Vehicles make it easier for us to connect with others and create new experiences through travel. So, it's a bit of a mixed bag with pros and cons to think about.
