You know, IMHO, any of the ones on the bottom, haven't been active at all, no or one tank ... I don't think it should be used for computation.

I would say if there was a way to edit the programming to not use a car in the average if it has less than 3 tanks ... then it will eliminate some of those that could possibly have been a troll entering a low tank, take out someone who signed up a long time ago and never returned ... So there is only 1 tank or less. This way, it doesn't just take out low mileage, but the high ones with one or two tans as well ... so it doesn't mathmatically skew the results higher, but make it a bit more realistic.

I also think the individual car's average should be solely that of the person driving it. That way if they bought an abused car, it doesn't affect that person's mileage, and in the same, a person who drives a little more aggressive doesn't get a bump.

I personally would like to see it top 70 mpg.

I would also like to see what effect something like that would have on all the other cars averages.
