 So it's just like a ginormous golf cart. Mike Roth hears from truckers like Totoro all the time. He's executive director of the North American Council for Freight Efficiency, a trade group started about 15 years ago to help the industry save on fuel. People have asked me lately, what happened to you, Mike? You were a diesel trucking guy, and now you love battery electric trucks. What happened? I mean, I remember the first time I heard about it, I'm like, yeah, right. I mean, that's okay for cars, but we'll never haul freight with batteries.
