People are weird about their cars and make major errors in judgement as a result (e.g. we tolerate incredibly high rates of people getting killed because they were "hit by a car", as though the driver had nothing to do with it). Pushing back on that is absolutely worthwhile.
No, in general I don't buy this idea that if we start using awkward phrases like "died by suicide" everywhere or avoiding phrases like "car accident" (which, despite what advocates claim, is a literally accurate description of unintentionally hitting someone or something with your car) but avoid changing any of the circumstances that cause the behavior it changes anything.
