My first thought is that Toyota needs to license this for their hybrids, and mount it on/as the flywheel. Using something like this as either MG1 or both MG1 and MG2 would seriously minify their hybrid drivetrain.
Because hybrids are the next step until EVs reach the junction of affordable and practical for the average household. Toyota knows this, and is playing it safe until there's a mass-market demand, when they'll step in with the most practical and boring EV possible.
