LOL I feel the same way! I bought mine on June 14th. I've got 259 miles on the car and the gas gauge is only down 1/3 from full and my average MPG is reporting 40.5 so far.
I have been amazed at how often the ICE stops. Anytime I'm doing around 40MPH or less and lift my foot from the gas it stops. My last mile or so to the house is a slight uphill in a 35MPH zone. Most of the time the ICE is off the entire way, only dropping the battery one bar. Sweet!
