So, the odometer is purposely MORE accurate than the speedometer.
And, I *see* that ≈+2 mph offset on my SGII on both 2004 & 2009 Pontiac Vibes, 2011 Chebby Cruze, and newest 2014 Prius. So, it looks *universal* to me.

Thats interesting. Ill have to double check my cts, but the gauge consistently reads 1-2mph faster than the digital readout.

2.3% optimistic seems like quite a large error for the odometer. I wonder if Nissan did this intentionally, or if it's just the tires that are being used.
I don't know about the accuracy of the odometer on the TSX yet, but the speedometer under-reports the speed by about 1%. At 60 MPH indicated, I'm actually doing 59.5 MPH. Of course, I have an analog gauge, so there is some interpretation error.

I know for many evs they either do not have regen braking or the regen is wasted as a surface charge if the vehicle is equipped with lead acid batteries. I believe with the leaf its able to take it all in and allow you to successfully reuse it on your next launch.

When I get an EV, I will drive it as quickly as I believe I can get away with while maintaining safety. At 1/3 the cost of gasoline, I won't care if it cost me an extra $0.05 on my round-trip commute to work. If I find free charging at work, I'll care even less about efficiency, although I will maintain some habits such as coasting and attempting to use regen braking instead of friction braking.
My attitude will completely change when I have range anxiety about making it to my parents house 70 miles away on a dark and cold winter night. 55mph and just enough HVAC to keep the frost off the windows.

My guess is that it is the tires - this is the Leaf S with 16" steel wheels, so I think the tires are a slightly different size and/or model from the higher trim levels with the 17" alloy wheels.
Our car has Bridgestone Ecopia EP422 205/55-16, while the SL and SV models have Michelin Energy Saver A/S 215/50-17 standard.
Edit: I checked the stock tire sizes; the Leaf S have an OD of 24.9", and the SL and SV models have 25.5". Guess what?
25.5" - 2.3% = 24.9135"

We drove farther yesterday than even the day before: 96.6 on the odometer, which is 94.37 miles. Unfortunately, we won't be charging it at home - because (fortunately?) it is at the dealer to have the leaking windshield fixed. They will likely charge it for us.
It has 12 miles left when I got home. It charged a few hours and it got back up to 29 miles, before we drove it the ~8 miles to the dealer.

Id call the dealer before hand. I had an electric wheelchair that was nearly dead and the shop did not charge it. When I went to pick it up it was in limp mode with a low battery alarm. I just left it there after tearing into them and continued using the rental as it didnt have enough power for me to get home. They charged it, but charged my insurance a charge and I had to fight that, but did win.

They have a public Level 3 quick charger, so if they didn't charge it, I will. :-)

Our '15 Leaf S had a leak at the top center of the windshield. It dripped mostly into the cup holders, but also on the shifter and a bit on the lower center dash. The fix was to replace the windshield. It was not a quick fix - maybe because the glass vendor didn't have a Leaf windshield handy? We dropped it off Sunday night (to make a 7am Monday appointment) and got it back Wednesday evening.
Oh, and they didn't charge it, so I get to measure the charge. It was back down to one bar, and ~14 miles left. So, I will continue the energy log to tonight's charge, and all the mileage since Sunday morning. (See post #64 above.)

How much range was left when you dropped it off?
Do you think they drove the car while it was in the shop? I've heard of mechanics using others cars for personal trips while they "work" on it.

^ +1! One mechanic lent my car to his daughter after he serviced it and she decided to stay out for hours after the appointed time for me to pick it up...
Needless to say, when I finally got it back they never saw it again.

It was probably about 20-21 miles when we dropped it off and it had 18-19 when I picked it up. The drive home is ~8 miles, so I managed to arrive home with ~14 miles.
We couldn't finish the charge back to 100% by this morning (stock L1 12A EVSE) but we should be able to get to 100% by tomorrow morning. I'll post it tomorrow morning, and drive it tomorrow, while my xA gets a new exhaust manifold.
