Spoofing Carwings

Thu Mar 03, 2011 8:27 pm

I don't spend a lot of time looking at Carwings anymore. I drive pretty much the same routine every day, so there isn't a lot of room for improvement. I get anywhere from 3.5 to 5 miles/kWh. I'm gradually slipping off the 'top 100' list, as are most of us. I'm still puzzled by the folks I see getting 8 miles/kWh. I can't imagine how they do it, unless they never exceed 20 mph.

But I got to thinking about how some folks might manipulate the system, and I suspect that it would be pretty easy. I have my account set up to upload my trip information to Carwings when I start the car for the next trip. There is no option to send the info when you shut the car down, which would be my preference, but you can have it uploaded every half hour, hour, or whatever.

So, the last trip's info doesn't get sent until I restart the car. And from what we've read, it won't get sent if you fail to press the "I agree" button that pops up when you shift to drive. If I don't give authorization, does that trip info gets lost when I restart the car for the next trip? If so, I could filter out any data that I didn't want Carwings to see. For instance, I could drive to the top of a big hill, shut the car off, restart the car, and refuse to send that data to Carwings. Then I could coast down the hill, turn off the car, restart it, and upload the high mileage data.

It wouldn't be too tough to spot this manipulation; my 1000 miles per month might drop to 100 miles/mo, but I could be the Carwings king! Eight miles/kWh? Child's play. I could probably do 100.

I think people who are getting high numbers are probably city dwellers in Japan who drive in the neighbourhood at low speeds and no heat ....

Perhaps more to the point, it sounds like carwings has no real utility to most consumers.

It would be useful if it were accurate. I'm collecting info to file a bug report.

Can it just be turned off? I mean turn off the whole screen of the center console. I think I would only want it on to use the navigation.
And I only need the navigation once or twice a month max.

Other main CARWINGS problems:

It can Start a car charging, but not Stop it.

It (maybe) does not give a "Charging Interrupted" message.

It heats or cools only to 77 degrees, not to a user-set temperature.

It does not (yet) provide any charge-station locations.

When it does show locations, it might not show available times, fees, status, or number/types of plugs/sockets.

I didn't realize that, I just figured it would use whatever the climate control was set to. Though I did think it felt kinda warm in the car in the mornings... So much of their materials say we can set the temp, so hopefully that's coming!

None of these are what Nissan shows in carwings. I'm only talking about driving and efficiency related data.

That is what I thought, so that is why I added the "OTHER Problems" list.

I don't think efficiency rankings are the main purpose of CARWINGS. It's a basic telematic system that allows owners to remotely:

-check state of battery charge
-start charging
-check when battery charge will complete
-see estimated driving range
-turn on or off the climate control system

Many drivers will find these functions very useful. I think you are trying to say that the eco-driving rankings compiled via CARWINGS is not helpful to you.
