Ferrari Mailing List: Re: Regen breaking

[Doug & Terri (dnt]

Good point Hans -
But, um, lifting and getting a rapid KERS decal is somewhat more surprising 
than routine coasting and down shifting - possibly.

Picture this - when we auto crossed in the 70's and 80's I would disconnect my 
brake lights so my competition wouldn’t know when I was braking.  One time at a 
particularly tricky part of a course I had to brake heavily then accel out.  My 
number two competitor thot - hmmmm, Doug didn’t brake there - maybe I can do 
that too?  He tried it and tore down half the course.  Heh heh..

Cheers
Doug

That is a valid point, but consider that the brake lights don't come on when 
you downshift a manual trans and lift throttle.  It's sort of the same 
thing.....
