Driving around Oahu this time of year requires very little AC, the terrain is relatively flat and the average road speed is about 35 mph. Very few open roads above 55 mph and the island is small. I did see on first recharge the average driving consumption was under 250 Wh/m which translates to 4 m/kWh so looks like a deteriorating pack. Need to inquire about usable range before next EV rental. Expected better than what was delivered.
