It depends somewhat on your definition of "critical. The 50s didn't have seat belts, and clearly most people survived. So "few" died in cars that there was opposition to year introduction.
I was recently in a country where smoke alarms are not "a thing". As is no-one had one, they simply don't exist. Sure there's the odd residential fire , but they're rare - single digits per year. Ladders kill more people than fire, but we sell a ladder to anyone, and you don't need a degree to climb one.
Building regulations are an important way of keeping people safe. They're a stamp of quality to buyers. Unfortunately they also seem to want to cover 100% of all cases all the time. And that final 0.01% is expensive, and time consuming. Which delays, or denies projects. Which results in fewer places to live. Which, dare I suggest, leads to homeless deaths.
Safety standards -are- important. Buildings falling down, or going up in flames, is obviously really bad. But equally not-building-at-all is dangerous. And regulators seem to give very little weight to that when adding another regulation.
