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?

A few reasons, but the biggest is time. No country could hit their commitments by gradually lowering emissions. If we want to hit below 2 degrees warming, cars will need to be emissions free soon. Gradual tightening of emissions has only lead to bigger cars and flat emissions
