don't you think that nissan would have produced this car to get max regen whenever they could as this would be a high priority on my list
They don't need to do anything special, the car is now capable of 80kw of regen, all designs like this are capable of as much regen as the max motor output. Nissan has chosen to limit regen in the software so they can provide a more blended response to braking that id just like a car, thinking more regen is going to terrify the general consumer. Making it the same as an ICE would feel. There are ways to offer selectable options here but in the end the LEAF will waste quite a bit of energy for some drivers to the brake pads as a result of this VS other EVs. Altering this is not that difficult in general but with their brake system it could be more of a challenge. At a min one could give the ECO regen on the D mode which is far more practical for most experienced EV drivers and more useful that the dummy pedal mode.
