This story is Tesla propaganda by a Tesla propagandist. The author of the piece wants every EV maker other than Tesla to go fail. Look at the history of articles the person wrote. No surprise, it’s another attack on an alternative green technology. I doubt the guy even cares about green technology other than what can promote Tesla.

There’s no reason to believe that this a serious attempt to go green. The vehicles are already diesel-electric so it is simply a matter of hooking them up to electricity. And since diesel is not that cheap, you can get save money with an electrified system, provided you have no interest in ensuring green electricity.
