Soon after acquiring my Volt in December 2011, I registered at voltstats.net and began tracking my efficiency performance. Despite many who had thousands of miles already logged in their Volts, I was confident that I could steadily increase my ranking over time. In those early days, that's exactly what happened. As I drove more and more in EV mode, I quickly fell into the top 100. Then I steadily could check my daily improvement in the ranking until ... one day when I started to slide in the other direction. "How could this be?" I asked myself. I was driving almost exclusively in EV mode. I seemed impossible to imagine that I could go down instead of up in the rankings.
Then I realized how much of a game changer this car is. As more people acquired and started driving the car, the more people that were driving almost exclusively in EV mode. At 95% and 473MPG (as of today), it is nice to see others doing even better.
So while I will likely continue to slide in the ranking, I take solace in knowing that it's not because I'm doing worse. It's because so many others are joining the group and doing - if only slightly - better.
