What you are saying is that if you park your car at a rest stop and eat dinner and then get back into the car, all the range losses that occur when you are eating can't be counted when calculating the range of the car. I guess that's OK but it looks like the Model S loses more range just sitting there for eight hours than the Leaf has in the first place. Basically the deal is that if you're going on a trip in the Model S you can't stop! No pedal to the metal but definitely pedal down. :lol:
The range isn't really lost. The range shown on the dash is estimated in part by the current conditions. If those conditions worsen after you park, such as if the batter pack cools off, the estimated range will be less. There are also vehicle systems that will draw a small amount of power even when the car is off, so that will also lower the range estimate.
So when you start driving again you will regain much of that range. A good example of this can be seen in a consumer reports piece : http://news.consumerreports.org/cars/2013/02/tesla-model-s-winter-chills-limit-the-electric-cars-range.html" onclick="window.open(this.href);return false;
The weakness in my mind is that the Model S should let you display the estimated range rather than the 'Rated' range just under the speedometer. However, it is easy enough to see in the energy graph and actually is very handy as it allows the user to get an estimate based on the last 5,15 or 30 miles, or even an instantaneous estimate (although I don't find that one very useful myself).
