A 2025 GMC Sierra 2500 is a way bigger vehicle than a 1995 Ford Bronco. 7,417 lbs vs. 4,616 lbs. and hood height of 6.6 feet vs. about 3.7 feet. And the "light trucks" category has risen to 65% of the market from 36% of the market back then. There are a lot more of them, and they're a lot bigger.
I would say that since ~2008 there have was a large increase in distractions for both drivers and pedestrians in the form of screens with a further additions in vehicles later aa well.
Add in the absolutely stupid design of larger passenger vehicles and you get the current trend.
You can’t probably blame 100% of that difference on the design standards of US vehicles. But probably a high proportion of them!
