 After owning a Ford Focus EV for a year, I advise consumers to be very skeptical about them.  I loved it at first, until the battery died several times at stop lights!  We were told it needed a software update to fix the problem.  That seemed to work for several months, until the battery died completely again.  Having an almost brand new car and then having to deal with towing, figuring out how to get to work with out it, etc., is a tremendous hassle and downside.  There are no substitute cars because substitutes won't be able to use the car pool lane.  Dealers have very little knowledge about the Focus EV, which also is incredibly frustrating.   Overall, a very bad experience with this car.
