I think this was always bound to happen, rent seeking behaviour you know. customers used to pay $3k on petrol let's say customers do 80% of charging at home, and as result say they "save" 2.7k per annum. fast chargers knows they have this pie and they want it. so they'd rack up prices potentially beyond petrol costs, since they know customers are paying way less 80% of the time, and they want to eat that pie. competition can drive it down, but only if competition are introduced. local gov or any private bodies able to identify positive externalities will need to introduce a 3rd party to keep fast charger prices slightly closer to cost. otherwise I'd be seeing two fast chargers at all choke points, profit sharing; duopoly charges monopoly prices, and every choke points are monopolistic.
