I got to witness a woman crashing on a MUT with her baby (helmetless) in a backpack carrier on her back.

The friend I was walking on the MUT with was so upset by the carnage that I never did find out if the child survived. We had to walk away or my friend would have fainted or puked or something.

I agree, adults are one thing (mom wasn't wearing a helmet, either) but children are something else entirely.
