Which is completely unregulated with anything like the same strictness.

I can only speak to the day trip side, not long-haul multi-day freight. But based on annectdotes, I would say there's (on average) at least one incident per month per driver where the truck has to be driven off the road to avoid a collision with physics-ignorant non-trucking traffic.

A friend of a friend was involved in an older lady's death after she pulled out right in front of him (as in, "even the brakes can't slow a truck down that fast" close). Of course he survived in the larger vehicle, but now he has that on his conscience.

I don't dispute that freight trucks are dangerous vehicles. But generally speaking, their drivers are far more experienced than you or I - they should be, they do it every day.
