The real game here is called "Im a Passenger" because this game is going to constantly force you to claim to be a passenger. Due to the its fundamental inability to distinguish between a GPS glitch and a moving vehicle, you will face this question even if youre walking down the street. The message can pop up at any time: Trying to carefully aim at the rare mon? So sorry. Its time to answer the are you a passenger question (hint: theres only one answer!). Trying to claim that gym you just cleared? Nope! You have to say youre a passenger first!
Also: gym rewards are now hosed. When a pokemon comes home with zero reward to you after standing in a gym for days and days? Thats just wrong.
