This is a big issue with me. One pedal driving is one of the best aspects of an electric car. The Chevy bolt I had was a perfect example of regenerative braking done right. I almost never had to use the brakes on that car. The Regen was effective and very aggressive. It also recouped most of that lost energy that would have been converted to heat in the brakes. Our Leaf Plus (which my wife wanted for its comfort) has a very weak regen system. You have to use the brakes more and it does not recover as much lost power when stopping or slowing down. I hope that Ford does it right with a very aggressive regen system that will let you truly do one pedal driving. At least there should be a way to vary the regen rate if you wish to.
