It's pretty easy to note a problem, and can be worth noting it. It's much more difficult to contrive a practicable possible solution. When asked if I have one, I'll just ssay "no" and move on instead of saying "Well, if people were smarter ...".
It's parallel to complaining about other drivers, a thing my wife does a fair bit. She doesn't understand how I can be so blaise about it. I guess it makes her feel better or something.
