I rather disliked the guy I saw riding no-handed (and without a helmet) and talking on a cellphone while riding on a busy MUP with a child in a child seat on the back. Feel free to Darwin Award yourself for stupidity, but please don't do it with your kid on the back.

I seriously thought of stopping the two bicycle cops I saw a few minutes later and asking them to read him the riot act, but decided it wasn't my business to interfere. Did I do right?
