I'm on my 2nd 2012 leaf. I drive in eco mode roughly 100% of the time, and I enjoy trying to get my mileage as high as possible.
Last week I test drove a Tesla Model X, just for fun. I was really surprised by there acceleration curve. Basically, they tell you you should never need to use the brake, except in emergencies. So they have extremely aggressive regenerative braking, that's aggressive enough to slow you down to a stop. Just keep your foot on the accelerator, release the pressure, and you'll slow down to a stop.
This intrigued me because they are obviously playing to the strengths of an electric car, instead of trying to mimic a gas car. With a little bit of driver reeducation, and positioning this as a positive, they are able to maximise the mileage.
Is it possible with something like leaf box to try such an aggressive regen on the leaf? If you were to disable creep, and be able to use the regenerative braking for the majority of your stop-and-go traffic, I'm curious how many miles you could regain. Has anybody tried this?
