For the Leaf integrating with Leaf Spy could do it, I think it is a lot of work with minimal returns.
Since I have moved into a CARB car with no support I really have no real interest. My car works for me even with an 87 Mile range. I plan to return it at lease end so I am not worried about the battery. For sure it will make to three years.
My totaled B had 14 months left on a three year lease and 9023 miles. As a retired person I do not drive a lot.
The Leaf is unique in that there is major hacking support. No other car I have ran across has the degree of support. Certainly not the B250E.
2012 Cayenne Red SL traded for:
2013 Pearl White SL Premium
Traded for a Cirrus White 2014 Mercedes B (totaled)
2016 Urano Gray eGolf SEL w/ drive assist
Loved the VW but it sat too low for my old body
Back to a Cirrus White 2017 B250E
