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.

Some fraction of x is always less than x, even if that fraction is very high. It would always be more efficient to avoid spending energy than attempting to recover it.
