The amazingly elegant out of the world hockey puck shifter and the digital speedometer are the two things I love in my Leaf.
adric22 said:Nubo said:ya, that is basically false. With a good analog dial I can tell my speed within 1mph without taking my eyes off the road. If I want to stare at it I can probably make out to within 0.1mph or less. I can also detect the rate of change quite nicely and catch drift long before a digital display clicks from one integral number to the next -- which can cover a 2mph spread. Second-order information such as rate of change is obscured by a digital readout.
Keep in mind that every since around 1995, all speedometers are essentially digital behind the scenes, taking their information from the VSS (vehicle speed sensor). So the only reason the digital ones don't reflect the rate of change very well is because they are programmed not to update but once or twice per second.

Almost all speedometers read conservatively high, either due to governmental regulations and/or OEM policy.Bob said:So if all vehicle speed sensors are digital, why are they not accurate? With GPS and simple software, it would be easy to self-calibrate.

My thoughts exactly. Nissan really needs to give existing LEAF owners a reason to upgrade to another LEAF. A larger battery and a real charging network would be enough for most people.abasile said:I doubt that LEAF owners' perspectives on speedometers are all that unique relative to forum-posting vehicle owners in general. So I'd be skeptical that there's much for the Advisory Board to add to Nissan in this area.
On the other hand, EV-specific input relating to concerns such as battery capacity, driving range, charging options, etc., ought to be very relevant, IMO. ;-)

My specific complaint is that I can't get the Progressive Snapshot discount on the LEAF. There is much debate, some hate it as intrusion, which it is, but it also helps to make people better drivers in my opinion. But if you're excellent, which I have proven on the Prius that I am, you can get a 30% discount, which is a huge savings.
If Nissan can't make things compatible, someone at Nissan should work a bit with Progressive to come up with a LEAF snapshot device.
My only other comment is about the QC network, which now is mostly on dealership lots. It has improved greatly in the past year or so, but I was prevented from making a 1200 mile round trip because I'd have to return on a Sunday and the dealerships were closed. So I ended up not being able to go. I understand dealership security, but still it should be possible to install the QC somewhere on the lot so a LEAF could use it even when the dealership is closed.
how does LEAF Energy compare as an app for accuracy?JPWhite said:Lots of the thread is devoted to analog v digital speedometer discussion.
The solution is clear to me. Give the customer the option since we seem to be evenly split. My $1,000 desktop computer or $500 laptop can have a analog or digital clock, why not my $30,000 car?
Tesla give their customers many customization, Nissan need to learn the same trick. Default choices for those who don't care, options for those who do.
As for the GOM. Pay the author of LEAFSpy for his algorithms and implement them in the LEAF. With the latest adjustments for cold weather/battery LEAFSpy is accurate within 1 mile over a 38 mile one way commute. Here's how I achieve that amazing accuracy. I read the miles/kWh off the LEAF dash and put it into Leafspy. Bingo. Nissan could feed the miles/KwH automatically into the algorithm. Don't make me think!

one reason why (actually there are several) I like LEAF Spy in that it allows you to enter your miles/kwh. Each driving condition and style along with weather and traffic creates nearly infinite possibilities.JPWhite said:thankyouOB said:how does LEAF Energy compare as an app for accuracy?
It seems to be a little optimistic in arriving at the miles/kWh and therefore overstates range by a little. It estimated I would use 9 fuel bars at today's speeds, temps, and elevation change but I actually used 10. It estimates I would get 4.4 miles/kWh when reality is closer to 4.
So I would say it is a little too optimistic by maybe 10%, but much better than the GOM.
Its been a while since I used the app. I have it on my iPad which I don't use when I drive. Thanks for reminding me I had it
