I think a better idea would be removing the footprint (square footage) calculation from CAFE ( I know it's an American standard but we also use it and their market heavily impacts what vehicles we get regardless). As it is now, it penalizes smaller more efficient cars for not being more-efficient-enough over big trucks. I don't know about you but I'd love it if we got an influx of small hot hatches and compact pickups, they might not be as efficient as some of the small cars today, but likely better than all the boring and not-great-at-anything compact crossovers we see so many of these days.

That's a decent idea.

Also, for comparison, my first car, a 1991 Pontiac firefly (don't worry I never use that as a security answer), weighed about as much as an actual firefly.

On a windy day I would have to steer into the wind to no be blown off the road.
