No, I'm addressing what you're saying. You tried to say that regenerative braking produced a net advantage, but this is not possible. Here's the source of your error:
> More stop and go with normal braking: -50% efficiency
Wrong value. Apart from the fact that the number is invented, because each stop turns all the car's kinetic energy into heat, the number should be -100%. Either that or perform a full analysis, with a listing of all the factors.
After you recover 20% of the energy with regenerative braking, you end up with -80% instead of -100%.
