We have driven our 60KWh Tesla MS for over 5,200 miles so far in about 4 months. We are averaging a rather surprising 291 Wh/mile. My wife drives it most of the time and yes, she is a 'safe' driver; always drives at or below speed limit.
I know it's not really an apples to apples comparison as terrain, weather and driving habits vary. But I thought it would be a fun exercise as many of you by now have several months under the belt and have a meaningful 'average'.
Type away :-)
