The more I think about it, the more I think that range-extended EVs (like the i3 or Volt) are really the current 'sweet spot' for EVs. This may change over the next 5 years, but for NOW I think they offer the best solution.
A 'plug-in hybrid' with a range of 30+ highway miles on battery handles the vast majority of *most* people's driving, while not getting 'stuck' because the battery is empty - use the gas engine. Most people drive under 40 miles a day. For the majority, charge overnight at home every night and the 2-3 times a month you need to drive more than 35 miles in a day (and can't find a plug) - you burn gas. You aren't hauling around a 60 kWh battery (10 will suffice). Almost all of your driving is pollution free, yet you aren't 'stuck' when you need to go further. The manufacturer can design the battery system with lots of 'spare', so the battery is never within 6% of total full or empty, increasing the lifetime of the battery. For those people who often drive more than 30 miles/day, they get a PHEV with more electric range (80 miles electric, like the i3), instead of the gen-1 Volt (40-ish). I think that the current crop of Ford PHEVs and the latest Prius PHEV just don't have enough electric range - ranges in the 20s really aren't enough, as you'd probably be using the gas engine every day (unless you had a pretty short commute and/or can charge at work as well).
My 80-ish mile range BEV is fine for 95% of my driving, and my old gas car (40 mpg) gets driven maybe once a month when I have to go far away. The BEV+old ICE for backup works just great for me. When my old Corolla dies, I think that I'll buy a used Volt to replace it. I'll probably also have a Bolt (or some other) 200-mile BEV as my main car, but having an inexpensive, mostly-clean second car that I can drive to SLC with 15 minutes notice (that's over 700 miles and 12 hours of driving) or Eugene (~600 miles, 10 hours) would be even better.
