Perhaps that was the results of their analysis, I don&#x27;t know.  I used to have a 27 mile commute in the Phoenix&#x2F;Scottsdale area, so even the 53-mile range might not have been sufficient.<p>Every extra 10 miles you add to the range will make the vehicle that much more useful for a wider category of drivers (in terms of staying in electric mode and avoiding burning gasoline).  At some point perhaps they see it as diminishing returns, except that really when it comes to electric vehicles, the more range the better.
