And to your point, yes, that same logic would aplly to a ton of high risk occupations. There's building construction techniques that cost more but have less risk, but we won't apply them where there's no pressure to do so.
Are we letting them die then ? I don't see the hyperbole in saying yes, as a society we're not willing to put the money to reduce these deaths. I see it as a part of life, and don't think we'll change much even as autonomous vehicle come (if they kill 1 in 10000 people but cost way less than now, we'll swallow the pill collectively)
So, ignoring the fact that society doesn't just get together every year and decide to let people die, I'd say it's absolute cynical hyperbole to say society is "letting truckers die".
I think it's a poisonous to ignore that tradeoff and wash our hands of the whole issue. It's like eating meat ignoring where it came from. That doesn't mean we all take extreme positions and become vegetarians, but it's not something we can completely ignore saying it's hyperbole or cynical to recognize as a fact.
Neither are true in any useful, productive sense. It's pure cynicism and myopic.
And you're ignoring the fact that not requiring a driver is significantly cheaper. And when it's speed versus cost, cost generally wins. So yes, society is absolutely going to be fine with trucks pausing in bad weather, because it means cheaper shipping.
(And stuff that is urgent and requires next-day delivery is sent across the country by plane anyways, not by truck.)
