Yes, you are right. If we assume 100% highway usage - then just simple physics says, that LeafBox cannot help with range.

Whole improvement comes from city driving, moderate long distance journeys, living in hilly region, or mountains.

Since I'll be extending my lease again, I'm interested. I drive mainly secondary roads at 30-50MPH, with some highway use at 55MPH. It's moderately hilly here. Any idea how much more range I could get?

After collecting all data from testers - it looks, that 10% or more (more city drive = better result). This also depends on drivers' skills, as huge part of range improvement comes from using "coasting/gliding" function of LeafBox.

I'm pretty good at coasting (my Vectrix motorcycle will coast), but rarely bother to shift to R/N to do it. What's the process? Are you still testing, or selling or renting it?

It is a finished product, available from http://vtechtuning.eu/leafbox.html

Let's say it is a "half-commercial" product - I use money to develop products for other EV cars.

As described in the videos and the first pages of this thread; LeafBox changes D mode to "Glide" mode. In this mode the "dead zone" of the pedal is larger to allow your foot to easily rest in a position where the motor will go to 0 kw/neutral. The stock Leaf already does this but you need supreme foot control as the pedal "dead zone" is only 1-2cm. This way you can cruise in D and with just a movement of your foot instantly switch to neutral and coast at maximum efficiency and not have to deal with the shifter at all.
