As electric vehicles are new you need to gradually ease them in... my hypothesis is that you have had 25 odd sat at the factory for a while.
You also have to think as its new the electrics are mega sensitive so any minor issue raises a red flag whereas an older bus would of been ok to go.
also electric buses are different in terms of traction
what no one has noticed is do these buses have a shut off button or do you need to cut the wires?
