You're absolutely right. If motor vehicles were banned, our environment would benefit from reduced pollution and healthier air. It's a great point. However, we also have to consider the disadvantages. Going back to a time without vehicles might not be the most feasible option since we're constantly striving to evolve. Plus, it would create challenges in transporting non-perishable foods quickly. And you're spot on about the limitations in terms of social life and traveling to distant places. It would definitely make things more complicated. Overall, it's a complex issue with both positive and negative aspects to consider.
