A fair point, but even then 150 is probably on the high end. I commute 60 miles a day and made it through the first ~2 months using only a level 1 home charger (standard wall outlet). My total charge trended down through the week, and then made up for it on the weekend.

~10 hours of level 1 charging gives me about 50-60 miles. Slightly limiting for my commute, but all in all, not impossible to work around.
