With respect to the trend lines shown on the battery graphs: A straight line connecting two points ignores all the rest of the data. I would much prefer to see the traditional least squares fit to all the data points. I hope you will consider adding that.
And while I am asking for stuff in the raw data listing mileage as, for example, 1,243.7 miles makes it hard to cut and paste data as the target programs tend to assume CSV and interpret 1,243.7 as two entries of 1 and 243.7.
