For autonomous, you're maybe running 2-4 kilowatts continuous load for the computing? At least no more than that? Then you have 2 kW for the air conditioning, probably 2 kW for cooling of the battery pack when running hard? Depends on whether you include those in onboard tech. Seems like the Model S does around 35 kWh/100 miles, at 50 mph that's 17 kW average power draw at highway speeds. If you're stuck in traffic, however, it's far less.
