I live in Durham, where the ELF is built. The ELF is a pedal-and-electric-powered reverse tricycle with an egg-shaped body and a solar panel roof. It is certainly unique. A 360-degree view is available here. Organic Transit, the company that builds the ELF, states that it “gets the equivalent of 1800 m.p.g.”
What does this have to do with criminal law? Well, the company recently introduced the Tactical ELF, designed to “give[] [law enforcement agencies] the tactical advantage for community policing.” An endorsement from Duke’s campus police comments that “It’s like a small patrol car.” I doubt that the ELF is going to be a mainstream law enforcement vehicle anytime soon, but it did get me thinking about the fuel efficiency of law enforcement vehicles generally. This post summarizes what I learned.
