The day is coming when the combustion engine will be outlawed in major cities around the world. This article looks at the promise of 12 such cities that are planning such bans by 2025. They will also be buying all electric buses by the same date. It is an interesting development and may have a temporary effect on traffic as people will need either public transport or more expensive electric vehicles. The car culture is already being effected by this and other cities declaring similar actions. Many companies are creating cars that can either shift into an electric only mode, or are wholly EV. Hopefully this will not kill the combustion engine as I am personally a big fan of it and its history. However, it will help cut pollution and by pushing people into mass transit, it may alleviate traffic.
