Just thought I'd post my quick thoughts about this engine regen "problem".
Most cars now are programmable, recently I changed the settings on my friend's Sebring car and all I had to do was read the manual, follow some simple steps and if you did it correctly the car chimed. Sounds like another pretty simple fix, why not have it programmable like that?
However why not take advantage of the fact that we have a navigation system in the car and that'd be a simple interface for the "user" or driver to input settings on the car. I imagine you could make it as basic as; Active Regen On or Off? Or have "profiles" for drivers/driving modes.
Or my favorite; make use of that lovely GPS technology in the car and have the car's computer change settings based on either basic geological position or take it a step further and have it change almost constantly in the sense of; highway driving - no regen needed, hilly/urban area - regen on, and so forth.
I'd imagine Nissan going as far as geological area if they ever did do something like this, but it'd be nice if they allowed us drivers to input our settings on an app like Google Earth, you could literally have it set street by street. Sounds excessive, call me a dreamer, but I think with something as smart as an EV, it just fits.
Now besides all the above, if shifting into Neutral eliminated the regen brakes from applying, I think it'd be an acceptable compromise as I've been doing the same whenever I drive (ICE, but it's good practice for my EV right?
(Note: I'm just referring to regen braking when you have neither brake or accelerator depressed, not regen braking in general.)
