It was time for something green.
There are some downsides, though -- it really helps to have a garage and somewhere to plug in at home. Relying on public charging stations is risky, because the infrastructure just isn't there yet. Cold weather dramatically reduces the battery range -- much more than Nissan admits -- as does driving at freeway speeds. Even in average weather the range is at best around 70 miles. Recharge times are long. This is not a car for road trips. For many people in urban areas, though, this is an excellent second car. Work commutes, errands, and nights out on the town are easy and require no extra planning.
Anyway, I just want to say that there are people in this country who are willing to take a risk on new, green technology and put their money where their mouth is, and we are two of them.
