An enthusiastic hypermiler in a car
without regen will almost always go further on a given amount of energy than someone driving normally & using regen to recapture some energy slowing the vehicle down.
The hypermiler will only use as much energy as necessary to get the vehicle to the point where they can start coasting to reduce speed, where the "normal" driver will keep burning energy until they apply regen to slow the vehicle (more rapidly). The extra energy input + the conversion losses in regen = less efficiency.
Of course not everyone can drive without braking. So for the times you
do have to press the pedal to the left of the accelerator, regen would be more efficient than friction brakes.
