My understanding is that if you come to charger with a Que and you
do not have enough to reach the next charger and there is a que on
this charger you only charge enough to get home or to the next
charger which may not have a que.
Not a very good solution but it averages out the delays.
Use apps that list chargers not only on the main roads.
It will eventually be one of those things that Granpa talks about.
