I think that if the motor vehicle transportation system deteriorates, people will definitely want to develop vehicles that do not harm the environment, i.e. do not emit carbon.It can be a vehicle that reduces excess noise, powered by renewable energy, reduces accidents, and creates a beautiful, livable environment for people. I have seen a flying trending on Internet last month which many people thought they will soon start their operation. For me, you there's advantage and disadvantage of ban motor vehicles because it's will affect a lot of people especially the poor. Good luck @muja01
