Since I got my roadster (#1325) two years ago I have been playing a mind game while driving in an effort to get a picture of the battery discharge rate. Nominally I start off with ~180 miles estimated. I then add the miles driven and estimated range numbers to come up with a guestimate for that charge under the current driving conditions. As the miles driven goes up the sum of the two numbers seems to climb to as high as 200+ between 0 and 50 miles driven. The number then starts going down coming to as little as 150 miles by the time I have driven over 100 miles. I tried writing down the numbers while driving. NOT a good idea! I am now looking at using my GoPro camera to record the data for later analysis. Anyone been there done that?
