I remember they used to show bad car crashes as part of the training you could take to reduce the number of penalty points (Polish road code, accumulate 24, lose your driving license). My colleague, who was a bit of a petrolhead, took it. It made him drive safe(r) at least for a few weeks.
Safety is in bad company these days because it's so often (I'd say 10:1, probably even 100:1) presented by people who have ulterior self serving motives (typically they have no skin in the game and are just in it for the virtue points).
It's one thing to have a driver's ed instructor, your plant manager or someone else in a position of authority who presumably knows what they're talking about and has at least some semblance of skin in the game show you those things and lecture you about safety.
Listening to a bunch of Redditors and HNers and Youtube commenters, etc, etc. grandstand nonstop about safety, safety, safety, safety, even when the relevance of and pretext for such grandstanding is very flimsy is counterproductive.
You can't post about <subject> on the internet these days without some jerk swooping in and making some borderline irrelevant comment about safety in order to score cheap virtue points which then derails everything. Heck, just discussing it at the work lunch table there's a 50-50 chance the same derailment happens in real life.
Being told you need to worry about not electrocuting yourself when changing a tire on Prius or you need to worry about carbon monoxide when lighting a single candle doesn't make people care about safety. It rightly makes them annoyed and suspicious.
What a strange and cynical view to hold. Maybe people talk about safety out of a genuine care of others? Or maybe they are into doing things safely and like to share that.
My American school in the 1990s showed “Signal 30” in Driver’s Education class, a gruesome documentary film from the 60s showing deceased, disfigured victims in automobile accidents. Totally messed up to show kids that.
