car seat safety?

Savana • Married to my wonderful husband❤ my babygirl is due in March 👶🏽
So if you were to see a person putting their baby in wrong in their car seat i.e. Like chest clip way too far down, too loose, front facing.. would you say something? And if not why not? I feel like it's more of a educating safety topic then a parenting choice? I don't always say something because I feel like I'm offending but maybe they don't know?
