An unrestricted Plaid can do fewer laps at speed on the oval at Daytona than fingers on one hand. Still, it's an impressive 6 minutes (remember the high discharge rate halves the bat energy density) (600HP=600KW drain). No battery improvements are going to change that. Even so, I would be absolutely thrilled to own a Plaid. Sadly, it's out of my reach.
People constantly dismiss my points on energy density, instead saying "it will work" or some variation on that. Yet the real world is full of engines being asked to do real work. Every transport category airplane ever built is example number 1. Ships, Trains, Trucks, Tractors, etc. Our economy is not powered by "grocery getters" nor is the "automobile" the major contributor to energy use or pollution.
