Experience matters....
 

Wanted to see if FE goes up after drivers put some miles on their vehicles. Maybe the "break in" of the vehicle (and driver) matter...

Pulled all the Prius and HCH2 records where miles are above 15k. Also pulled the TCH where miles were above 10k.

It looks like the typical (median) driver for the Prius and HCH2 seem to get about 2mpg better than their entire groups average. For the TCH however, the median is not up (37 mpg in each case).

Prius still has a slightly higher median (1mpg) than the HCH2.

Also, the "90%" drivers getting 53-54mpg in HCH2 and Prius might get about 40mpg in a TCH.

All vehcles get better FE than my Jeep XJ did. :D
