That other vehicles are getting plug and charge is a sign of the lead eroding. They only have to figure it out the one time. I would expect battery production capacity to be somewhat lumpy (with big shifts when new mines or factories open). That can take a long time and I haven't looked at where things are, but it also means that there can be a very sudden shift.
