Greetings,
If we banned motor vehicles worldwide, it would definitely help reduce greenhouse gas emissions, which is great for the environment. But it would also make many human activities more difficult, especially in urban areas where we rely on vehicles for short distances. Even for longer trips between cities, driving or being a passenger in a car, motorbike, or bus is so convenient. It's hard to imagine life without motorized vehicles nowadays.

And you're right, there might be people who would violate the regulations or even protest against them because they rely so much on vehicles. But in the long run, this kind of regulation could have huge benefits for the environment, making the air cleaner and reducing pollution from vehicle exhaust. It's a complex issue, but it's interesting to think about the trade-offs.
