The title feel awkward, so if anyone can improve it, that would be great. Here's what I mean:
Sometimes you walk along the street and see someone in a car without a seat belt. Let's assume it's summer, the window is open, they're sitting at a red light or something and you could talk to them, even if just for a moment.
Or a bigger one - people who have children in their car without any restraints at all. No child seat, no seat belt, nothing. Sometimes you also see an infant in the lap of an adult. These can be seen in parking lots or when parents drop their children off at daycare - also times when it's possible to approach them.
These are all against the law, and if there was even a small accident, the consequences are potentially devastating.
Sometimes there are also smaller problems - an obviously wrongly installed child seat; a child seat that does not fit the child; etc.
It kinda feels like I should do something, speak out... but on the other hand, it's none of my business. Telling them flat out will most likely result in a hostile reaction. On occasion it looks more like somebody simply didn't know what they were doing (so they could even be receptive to corrections), but when you see someone without a seat belt, then that's obviously a choice and not a lack of knowledge. And if there's a similarly unsecured child next to them, who really doesn't know any better and was just doing what mom told them...
What should one do in such a situation? Can such people be spoken to in a manner that makes them reconsider their behavior? Or should they just be let alone and the natural selection allowed to take its course?
