Personally, I don't give a damn about the skirts on the side of trucks (not mandatory here, sometimes a problem due to the rougher terrain our trucks are more likely to traverse).
USA has lots of decent engineers. They could easily deal with rough terrain.
The one simple feature that should be mandatory that would prevent these and most[1] other accidents is an attentive driver in a reasonably maintained vehicle.
This is true, but we are dealing with human beings. They are a very variable species and subject to considerable weakness. Often attentive drivers in reasonable cars do everything right but still die because of other drivers who don't.
