The weight of the on board capacitors would in itself be an energy

And how do they get up to speed - magic pixie beans?

Stupid boy. You don't get anything for nothing.
But storing kinetic energy is far more efficient than charging/
discharging batteries.

Kinetic energy stored as vehicle momentum is of no use for accelerating
the vehicle. *At the time you need it it isn't there.

It's also of no use for climbing hills - the extra weight exactly
cancels out the extra KE.

In fact I can't think of a use for extra mass at all. *Except in a road
roller.

But it can be used for charging batteries. Which is exactly what
happens in electric cars. In ICE cars, it is lost.
Bad news during cornering though.
