I know, I know, those short rides may actually be less safe but, well, that's what I do.
That actually makes a lot of sense to me. When I putter about playing Pokémon Go or Ingress, or run some errands, I see no reason to wear a helmet. Look at the marathon runners who cover 42+ km in less than 3 hours. I often ride slower than that (14 km/h).
