I will be the odd man out here. I drive 52 MPH in the right hand lane of the freeway (405 and 101) when traffic allows me to go that fast, which it often doesn't. I ease out from stop lights, let others race pass me, then often pass them stopped at the next light because I have looked ahead and not wasted energy racing up to a stop. The example I am setting: energy of various kinds will probably be more limited as the years go by, so use it wisely. Surprisingly, I often find other cars content to go the same speed and not eager to pass. This is a very relaxing way to drive and only increases my commute time from 32 minutes to 37 minutes (average).
However, I do talk to anyone who asks about my Leaf, enthusiastically but realistic about the limitations of the current EV. A lot of people are fascinated and I can see their minds doing the computation, "Would this work for me?" I think this sort of "evangelism"--plus giving rides to family and friends--is a lot more important. People experience the Leaf as a real car, especially when they ride in it. I do briefly show them what the car can do if you want to zip away from a stop. They are uniformly impressed by the rapid acceleration from a stop. After taking a test ride, my sister-in-law told my brother, "We should get an EV for our next car."
