Hello @chant

The good thing about it is that they lived longer and my grand father died at the age of 119 years.

Your family's history sheds light on the significant shift in transportation habits over generations. While previous reliance on walking contributed to longevity, modern convenience often leads to less physical activity. Banning motor vehicles would present challenges, impacting daily life and potentially reducing opportunities for exercise. Motor vehicles indeed play a vital role in daily life but pose significant environmental threats. Their emissions contribute to greenhouse gases, pollute the air, and generate unwanted noise, all of which harm the environment and human health. Your understanding of what happens when a motor vehicle stops is excellent.
