The stupid thing with all of these fleet failures is that, if properly structured, they could be done in such a way that the electric vehicle makers are willing to give a significant discount on the pricing in order to be able to collect long-term data on performance to be used to improve the products. Development testing is great, but there is nothing quite like having hundreds of your products put through real-world testing.
And, to be perfectly honest, given the nature of the routes driven by many fleet vehicles, they are probably the class of vehicles that would be most likely to benefit from electrification in an economically rational way.
