I know that the heater is rated at 4kW on defrost, so is the AC the same?
The Roadster gets about 4 miles to the kWh, so assuming that the 4kW figure is correct for the AC then a half-hour traffic jam would use the equivalent energy for 8 miles of motoring (assuming that the AC runs constantly on full power during this half-hour).
