EU and US is just fundamentally different. It is hard to overstate that. But it comes with trade-offs. Workers in EU, in general, have better standards at work than in US. It helps that in EU, healthcare is not directly part of employer cost ( everyone pays into it ). EU tends ( I do mean tends, because it seems to vary greatly ) toward unions, whereas US truckers seeem un-unionized by and large.
US is a weird place sometimes. Business/Money trumps safety. Regulations are often met with huge push back even when they can potentially save lives.
