Charging Costs for Tesla in US

Please consider adding a cost computation back in for Tesla in the US. It used to be available and when one compared alternative routes the cost in $ was also displayed. We all know its not perfect because of the rates changing with time and at each supercharger. Why not use an average value cost per KWH and make it available to change per user so we can get a ballpark idea. Very useful when comparing routes and seeing the difference for ICE car costs
