Vehicle fuel economy is regulated for all new vehicles in the US. There is a curve that as the vehicle gets bigger, the less fuel efficient it needs to be. So cars in the US will continue to get bigger because it is cheaper than making them more fuel efficient.

That was an interesting read. I’m from Europe and unfortunately the trend of bigger and bigger cars has made it’s way here too. Not as much as in the US but still. It really encroaches on both space of pedestrians and cyclists when a dozen of them are parked in a narrow alley/street. Also makes it very hard to see children weaving through the gaps. I think consumer vehicles that are too big should simply be zoned out in inner cities where space is limited as is. Every year the cars grow bigger but the streets stay the same.
