This is a good point. Early model range was still too low (I have days where I end up driving a couple of hundred miles on little advance notice). But given a realistic (not some next-to-impossible "ideal") 300-400 mile range, in most cases when I need more than that I know about it far enough in advance to arrange a rental. That also assumes that total cost of ownership is lower by enough that it's practical to use rentals as a "second" vehicle and still come out ahead.
