400 is about right.

negative reduction!!  Or are you one of those free-energy fanatics who believe
that you can get more energy out of a process than you put in?

Come on!!!

You put energy into the car to get it up to speed.  Then you brake - any energy
recovered would be less than or equal to the energy needed to get it back up to
speed.  We all know from entropy, however, that you won't get all the energy
back from regenerative braking.  Therefore, and note carefully:

Stop and go driving will require MORE energy, not less.

That's right - why do you think city mpg are less than highway?  I mean, for
city dirving, since the velocities are lower, you fight less air resistance -
in you naive system, city driving would have better mpg.

You want 600 miles of city driving, even with regenerative braking, be prepared
for Gigajoule flywheels that will melt entire the entire vehicle and leave a
hole in the street on failure.

Really?  Hey, I got some prime Florida real estate to sell you.
We could really make some bucks off this pup's "faith".
