Because they can't bear to make vehicles smaller. That's the real terror on American roads. Something like 60% of vehicles are huge because it makes the driver feel better. And indeed, it makes the driver safer in a collision - at the cost of making everyone else in the area less safe. Something has to be done to stop this trend first and foremost.

After that, when vehicle sizes start trending down towards reasonable, we can look at getting speeds up without reducing overall safety.

I think the reason trucks are so huge these days is not the ride feel. It's the EPA gives more lenient pollution restrictions based on size of vehicle. So instead of making the engine less polluting, just make the truck bigger and keep the same engine. It's like a cereal box that's only 1/3 full.

		I believe it's a mix of both. https://en.wikipedia.org/wiki/SUV#United_States The idea to introduce light trucks in passenger-car shape to get around pollution limits was the car manufacturers' idea. However, the US public ran with it and bought because of the perceived higher safety and social status that comes with driving a larger, heavier vehicle than everyone else. And they continue to buy to attempt to one-up each other even though the pollution limits now apply to SUVs as well as smaller passenger cars.

		My understanding was that the American domestic auto manufacturers were getting their asses beat by foreign competitors who made much better cars. American companies could differentiate themselves with giant vehicles that wouldn't be practical in Europe or Asia. But because the giant vehicles became status symbols the low end started imitating them and now nobody sells cars in the US any more.
