JAC Motors, a Volkswagen-backed Chinese automaker, unveiled the first mass-produced EV with a sodium-ion battery through its new Yiwei brand. Although sodium-ion battery tech has a lower density than lithium-ion, its lower costs, simpler and more abundant supplies and superior cold-weather performance could help accelerate mass EV adoption.
Actually electric buses make a lot more sense, as the utilisation and environmental impact would be much greater compared to normal EV cars.
Plus you are conveniently omitted mentioning the energy losses of the cables, the maintenance cost, the installation cost, etc.
Not to mention how unbelievably ugly stringing that shit all over the service area is. Electric buses make a ton of sense.
