I'm still not playing "Pokemon Go!" but I did play "Pokekid Stop!" the other night.
I was driving the Wife of Bobmobile to get take out and had to change trajectory while entering a roundabout to give space for a kid - less than 10 years old, in the dark, wearing dark clothing, eyes glued to his phone and walking on the road (which has a perfectly functional 3 metre wide footpath on both sides.
I did a 3 point turn (when safe) and came back to point these things out and suggest politely that I didn't care what he was doing, just that he should do it on the footpath.
He ran all the way home. On the footpath.
