'Always' violates the specific attributes possessed by BEVs.
80% of 'braking' kinetic energy can be recovered into the battery of a BEV.
Zero braking energy of an ICE vehicle can be recovered into its fuel tank.
Also, the BSFC-e of a BEV is around 3.5 X lower than an ICE, so they're only using a fraction of the energy to accelerate a vehicle back up to speed.
The mathematics is significantly different.
