I have to wonder if this has ever happened to a gas powered cruiser. I mean, and no disrespect to any officer, but is it possible that anyone could forget to head out with a full tank / charge? Edit: or not think about it after a long shift, or otherwise find themselves low after several hours and suddenly in need of a full tank / charge?
Low charge, or heck any sort of mechanical fault. Flat tire, engine starts to miss, whatever. I'm guessing few pursuits get called off in general, and that is part of the reason for frequent fleet changeover, but it's bound to happen.
Personally, since this could happen just as easily for a gas powered cruiser, I'm going to file this as non-news.
