> if the majority of your time is spent spinning rubber fruitlessly at launch then you can begin to lessen the problem by adding weight to increase mechanical friction. It doesn't really work like that. Say you double the weight, but keep the coefficient of friction - you also double the force. But the now-doubled force has to accelerate double the weight, so the acceleration remains absolutely identical. That's a small simplification, because on snow, gravel, mud and other loose surfaces you have a more complicated relationship, but on asphalt it holds more or less exactly. The reason EVs accelerate better is usually because of instant, better-controlled and gapless application of torque and power - no shifts, no delays, no turbo lag, etc.
