"No Sightings when Travelling at Driving Speeds?"

#PokemonGO: As of tonight, my sightings keep disappearing when I'm in a vehicle going 30mph+ ... is this Niantic's new way of stopping people from playing while driving or is my game glitching? I've restarted the game and my phone, with no change in results. via /r/TheSilphRoad http://ift.tt/2dilMcQ
