So another cyclist and I are slowly riding back to our cars after riding 200km. A ~10 y.o. kid walking down the street very seriously informs us that we should stop riding bikes and take up jogging. I contemplated turning around and asking him if he could run 125 miles, but decided to ignore. I'm thinking this is a good demonstration of why you shouldn't whine about other road users while your kids are in the car. I don't remember being that rude as a 10 year old, that developed later in life for me.
