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.
