I Like the tree display. Its kind of like a game. I got three trees yesterday on my way home from work. :D

Somehow Nissan thought we are all idiots and will fall for that kind of juvenile nonsense. It is wasted real-estate space in the dash, and I would rather see GIDs or its equivalent in that space. The novelty wears off in a week..

Quiet everyone! Nissan will just remove it and put nothing there in it's place, except an obvious void where a part was deleted (like the driver side oh-shit handle, glove box light, etc...).

I like the trees and the dial that shows efficiency at a glance without taking eyes off the road. Its the best place because its right next to the MPH speedometer high up on the dashboard. The trees keep track of the entire LEAF's global fleets' CO2 savings which is something unique started by Nissan and now others are automakers are copying.
I agree that the incomplete tree shouldn't just disappear every time we turn off the car. The trees should resume building at least till the next charge. This would help us to see how many trees were made during each driving cycle between charges.
I also agree its like a video game and encourages efficient driving to build more trees faster.
I am also afraid that Nissan will just take it out and leave it blank if too many people complain, the way they reduced regenerative braking/coasting in the last firmware upgrade, and the way the removed the glove box light and left an open Chevy logo type hole there to mock us.

Sorry, but the trees are just a poor and highly inaccurate approximation of your CO2 production, and the so-called efficiency meter is a joke that fails to properly consider many aspects of the Leaf operation and is about as valuable as the old vacuum gauges on ICE vehicles decades ago... 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.

I'll give you but one of many examples. Coast down a hill in N. Press and release the accelerator. Watch the efficiency gauge go from 0 to 100%. There are many more...

Nissan screwed up with Neutral coasting for sure. I am with you on that one. In fact, I wrote something related to this topic here in Oct 2013: http://www.mynissanleaf.com/viewtopic.php?f=34&t=14729&hilit=N+mode+coasting+regen I later found someone else wrote a similar post here: http://www.mynissanleaf.com/viewtopic.php?f=11&t=11090&hilit=neutral+coasting+suggestion
