An entry level model S has a ~360hp engine, so 0.2 MW A million of those cars is 200,000 MW Amdahl's law: when optimizing performance, target the largest cons

An entry level model S has a ~360hp engine, so 0.2 MW A million of those cars is 200,000 MW Amdahl's law: when optimizing performance, target the largest consumer first. And in this case the engine is the largest, by at least 5 orders of magnitude It would save much more electricity educating people to drive less aggressively and use less braking than to remove the sensors
