1) If most EV drivers have a ~150-200 mile range almost none will charge anywhere except at home while in their home town unless it is free. It is a very rare occasion that most folks drive >150 miles within their region per day. I predict the death of most level 2 public charging as a result. Without the constant fear of running out most folks just won't bother to plug in at the grocery store, local mall, etc. There will always be a vocal minority that will disagree I am sure.
I can't imagine public charging stations will die out. There are EVs like Smart that cater toward a more urban crowd. Urbanites tend not to have home charging options. I imagine a car like the smart ED will also stick toward a <100 mile battery as the tech evolves, but will focus on driving the vehicle price lower and lower. Their electric lease runs for $1400 due at signing $139 a month right now, so I wouldn't be surprised if their electric leases get down to the same $99 price point as their entry level gas counterparts.
A super low priced EV would also mesh very well with the car2go program, and electric car2gos have little need for high range.
