But, wouldn't adding weight reduce mileage in a gasoline car?
There is no free energy. Of course petrol powered vehicles use more fuel when load on the engine increases.
But battery drain is a different phenomenon than a fuel tank depleting. As I understand it, oil based fuels provide much more energy per unit than electricity, so they cope better with greater demand on their output. I believe that when batteries start to drain, they lose efficiency and so have to direct more of their power to keep the machine functioning. Petrol engines do not lose power as their petrol depletes. A car with half a tank of petrol continues to function normally. A half charged battery loses power.
Electric vehicles have another serious design flaw; by definition they must carry far more weight unloaded than petrol vehicles because of the batteries they carry.
