Still silly considering their solution is a large amount of complexity for limited benefit. Most roads have lower speed limits (thus aerodynamic drag is not nearly as significant) and long-haul trucking isn't really a thing in the American or Aussie sense... Far more rail networks, less distances to drive. Like, they're being rolled out now... Electric vehicles actually make sense in Europe (distances between most places are short).
