Ina town near where I live they bought fully electric bus for the 2.5x the price of a thermal one. You may think okey that expensive because it is well though. But no battery isn’t heated so in winter the buses hold a quarter of a day with the heater, the cold etc. And now they break a mirror and they have to be carried to the garage for recalibrating because they refuse to start. On thermal bus they send a technician with a replacement mirror and one hour later bis is good to go. They got scammed hard.
