I do jackrabbit starts whenever possible and enjoy driving at or above the flow of traffic (75-80 around here). I get about 60-65 miles per full charge. I assure you that the marginal pleasure (along with POSITIVE externalities-- see below) I get from zipping around in the car dramatically exceeds the negative externalities of my reduced fuel economy.
In fact, I drive less efficiently (relative to max efficiency of each car) in the i3 than I do in two other cars I have that than are >500HP. Here's why: at a stop light when I floor a fancy high-power ICE car, it makes a lot of noise and people's heads turn and I am "that guy." I feel their scorn. So, not wanting to be an a**hole, I rarely do it.
In the i3, however, I silently launch into the sunset (faster 0-30 than almost any other car) and if people notice at all they think "wow, those electric cars are pretty zippy-- maybe I will consider one."
So, in conclusion: if you want to save the planet, drive the i3 at WOT as much as possible and, when asked about the car, ALWAYS lead with performance and acceleration and NOT with efficiency or ECO-friendliness.
P.S.: My PV panels made 1,900 kWh last month, so I'm good on that front.
