Yep, on the Leaf, the salesman will tell you to only charge it to 80%, not realizing that the factory parameters are already set to 20%@empty (0% on gauge) and 80% (100% on gauge), thereby having the newbie charging the car to about 70%! Surprise, surprise, the newbie now only gets about 65 miles on each charge (impressed much? I think not!), and starts talking about the less than promised range. Gotta love it!
