That would tend to make the battery-carrying impact even more on the
stop-start/short range electric car than the fuel weight on long

In the stop-start scenario they can (and do!) use regenerative braking -
recharge the battery with the motors instead of throwing the energy
away. That's what they are really good at - that and not having a
tickover burning fuel even when sitting still.

and my Mazda 6 diesel does both those things. It uses the regenerated
energy to power the starter.

For all of five seconds.

so? if it only takes 5 seconds to stat the car, why would you need it to
work longer? But in heavy traffic the restart is needed quite frequently.
