Geocaching took quit a bit of time before it reached that level.
I guess it wont take long before we hear about fatalities caused by Pokemon GO just like we do with geocaching. The players might be about the same kind of people for both games. I had some opportunity to witness a pair of players. The situational awareness is significantly lower with Pokemon GO as there is apparently no location that can be compromised.
I will defintely be more alert when driving my vehicles.
