You know you can stop in a gasoline powered car and take breaks if you want or feel tired. But I cant imagine being forced to take an extra 1-1.5 hours whether I want to or not.
Again the i3 isn't a great car for long distance driving due to small battery, and a big part of the extra 1.5 hrs was due to waiting in line for charging (summer vacation, yay). Both of those issues have gotten better and will continue to improve.
