On the shuttle to campus twice now I’ve heard a radio spot for the Nissan Leaf, an electric car. The spot finishes its pitch by urging the listener to buy a Nissan Leaf – doing so, the ad says, is desirable because “You’re not starting a revolution. You’re way past that. You’re joining a movement.” The first time I heard this I almost fell out of my seat, and I was careful to listen attentively the next time I heard the ad to make sure I had heard that right. There’s so much packed in there! What are we supposed to be thinking?
