Part of it is culture and general pathologies - the upper management still thinks hydrogen is a workable idea which would be a bit more faie back in the 1990s or 2000s when batteries hadn't caught up. Another factor is the general innovators dilemma where they have tremendous sunk costs in their old fuel burning ecosystem. To be fair generally moving from a mature and high scaled to an untested and new approach is expensive and downright reckless looking levels of risk, only vindicated after a success when the unforseen or unbelieved shoe drops.
