I find myself wondering why governments don’t continually ratchet up fuel economy standards, including on light trucks, and let the auto industry figure out the best way to meet them. Electric, hybrid, smaller, more efficient ICE, whatever it takes to lower emissions without mandating a specific technology.
In previous decades CAFE standards drove significant improvements, albeit with some really crappy vehicles initially.
Is it because with such a massive fleet of ICE vehicles on the road we need to mandate electric to meaningfully reduce average emissions?
