Both can be easily fooled.
What is so inaccurate about the ECO TREE? When we drive slow and don't step on the go pedal too hard, the tree builds up faster. When climbing slopes uphill if we maintain the same KWh, the tree continues to build at the same pace. If we start speeding and drag race at every traffic light, the tree build up reduces or stops depending on how inefficiently we are driving. Its not guessing anything, its giving us real time feedback from the way we are driving, the amount of energy we are using or generating, etc.
Besides the ECO INDICATOR next to the ECO TREE directly reflects how efficiently we are driving. When we coast, regen, drive slow and don't use too many KWh of energy the ECO INDICATOR shows that instantaneously which then builds the tree accordingly.
What more can Nissan to do make the tree building more accurate? Feel free to give suggestions on how it can be made more accurate according to you. Perhaps a direct satellite link to calculate the effects of the Earth's rotation on LEAF's drag will do it. OR a digital belt around the driver's waist indicating how our obesity is reducing LEAF's efficiency. Yeah that will make it accurate enough to satisfy us engineering geeky LEAF owners.
Its a different thing if you don't like this feature but calling it "highly inaccurate" and comparing it with some old analog ICE technology is absurd. BTW its CO2 "reduction" not "production". We reduce CO2 emissions when we drive LEAFs and we reduce it even more when we drive the LEAF more efficiently. That's the whole point of the ECO INDICATOR and TREE on the top left dashboard. Sorry for the rant.
