An easy first step would be making licensing more strict. Where I am there are classes of licence for passenger vehicles, larger transport trucks, busses, and finally semis/lorries. Each step up requires further testing and more stringent requirements.
I feel like it’d go a long way if your typical American pickup was moved up a class. How many people just wouldn’t bother with a big truck if it meant another driving test and visit to the DMV? Any vehicle over X height, X length, X wheelbase, whatever would become a “commercial truck”. Smaller trucks from back when they made small trucks wouldn’t meet the requirements.
Sadly I don’t think a politician running on a policy like that is winning an election anytime soon.
