Nissan should provide an option to toggle the trees display with little outlines of oil tankers, and the little tankers can slowly fill up as the number increases :)

The bubbles display is cryptic.. just use fast reacting solid bars to indicate power levels, and label them in kW or horsepower.. green in regen, white as you accelerate and slowly changing to red at the maximum levels.

Nissan is playing psychological tricks on the drivers with the existing GOM, so they are unlikely to give us true numbers unless they get rid of this idea.. ideally they should provide two ranges: one fast reacting based on your present power level and speed , and another based on your long term (weekly) efficiency and speed.

Yes!

From what I understand from the pro-tree people, it sounds like the trees are supposed to be a measure of efficient-driving-behavior, after normalizing away circumstances outside of the driver's control. (which circumstances? traffic lights? stop signs? congestion? outside-temperature? cargo load? passengers? AC thermostat setting?)

I very seldom see any complete trees. Is it because my trips are short? Why not make it trip-length independent by resuming tree-display across stop/starts?

Is there any write-up from Nissan about what the tree-display is?

What is the arc of dots surrounding the growing trees?

Now THAT ... I like ! :) And ... when you put the LEAF in Park, the set of oil tankers animates, slowly blowing up each one. If you don't power off, they silently re-appear as you continue the journey. In the alternative, they are "X'ed-out" like the fighter pilot tracking his kills on the side of his plane.

Thanks for the suggestion, Herm. 8-)

ya, pretty much. its not perfect but its a measure of efficient driving that is NOT based on your miles/K which is related but can be markedly different.

I very seldom see any complete trees. Is it because my trips are short? Why not make it trip-length independent by resuming tree-display across stop/starts?
i find it does suck that you cant have "trip" settings and the only reset option is to power cycle the car
Is there any write-up from Nissan about what the tree-display is?
yep. but we have gone over that. its a measure of how efficiently you drive. what gives you trees? smooth slow acceleration. maintaining constant level of power and speed. slow gradual stops. iow, driving efficiently
What is the arc of dots surrounding the growing trees?
"near" instantaneous feedback on how well you are doing. its not perfect by any means. in fact, try this. go for a drive, try to "peg" it to say... well, we will call it 15 pips (why i dont call it 10, i dunno) so if moving and you have say 12 pips for X seconds, eventually you will gain a tree segment. supposing we say each tree has 5 segments (once again, 10 would make sense, but just saying ya know) after a bit, park it. leave it on.

your tree meter will be sitting somewhere. say its the 12 pips. now the pips will stay that way...for a while anyway. but the car is on and using power but not moving which means VERY inefficient driving right...so, soon you will have 11 pips and so on as you sit there. if you sit there long enough, all your pips will disappear INCLUDING your gained tree segments. (i am guessing this takes about 45 minutes if you started with 7 pips)

now for some people; they will never see trees because
1) short duration drive
2) they drive inefficiently.

now, this is not really a good measure of driving efficiency because if you play with the trees you will see that as long as you brake slowly you can maintain the 15 pips. now what is better is maintaining near constant speed (which does gain trees but not as quickly i dont think. this is hard to quantify...or at least it is for someone like me and my patience level)

but general observations show that at speeds around 30- 40 mph, you can apply power up to 10 KW and stay pegged. in most cases, going up to 12-15 KW will drop you down into the 10 tree bar range. 20 KW will drop you into the 5-6 tree bar range.

now, if you increase speed to say 50-55 mph you will almost never see 15 tree bars, but 12-13 is doable if you are careful and this is with power up to the aforementioned 15 KW so the meter is somewhat speed dependent which means outside variables like elevation, wind direction, etc. will affect your #'s so the trees is not an absolute measure

It has to be in D or Eco and not moving.

how many trees have you grown this way? because mine disappear if i am not moving (along with my GIDs)

It happens to me when I am in very congested stop and go traffic where I am getting something less than 2M/Kwh with AC on, and yet I've grown two or more trees while going all of one or two miles over an hour or so... The Gids, bars, and efficiency drop but the trees grow...

you want to appreciate the dash and the trees, try on my shoes.
the car has been in the shop for a rear-ender since may 30.

no trees, no charging.
yesterday was -- fingers crossed -- the last commute without the car, which is due back Friday.

All this tree talk had caused me to log into Carwings for first time in about 8 months and I have my flora mixed up a bit. The LEAFs trees represent an amount of CO2 not produced. I guess I mixed it up with the Focus Which generates leaves based on driving efficiency.

So trees could represent the amount of CO2 a tree absorbs or in this case CO2 the LEAF did not produce

Ok I put the car in Eco and sat still for 15 mins - no tree nor even any stump. There was a full arc of segments which slowly dropped to none over a couple of minutes and my mile/kwhr dropped from 4.3 to 4.1 during this exercise so the idea trees grow while stationary is less than 1 tree per 75 mins. I typically see trees at the rate of one per 11 miles.
