It would be useful to show the actual detour time to go to a specific charger, counted from highway exit to highway re-entry to chose the best charging stop for route. Sometimes the app suggests a chargers that needs 20min detour, negating the benefit compared to stop at an earlier charger inside the highway circuit or just outside toll boot.
