And how would people on bus dump unwanted Pokemon and excess inventories, and maybe tag stops or snag a Pokemon? Shouldn’t need to punish people who rides public transportation because a few dumb drivers went and killed people playing the game.

Would be very unpopular with people who rides bus or train. Niantic already put the warning there, if someone is still going to drive anyway and gets in an accident, they will be charged and Niantic can’t be sued
