The lack of wet weather/rainy tracks in Gran Turismo Sport is kind of disappointing. Well Polyphony Digital is now promising more wet weather tracks will be added to the game in future updates.
This was confirmed by Polyphony Digital’s Kazunori Yamauchi who was recently interviewed by GT Planet. He said “yes” to more wet weather tracks being added to Gran Turismo Sport.
He also said: “It’s just a matter of adding wet conditions to other tracks through updates. All of the cars in the game are already built to be compatible with rain and have working windshield wipers“.
That being said, not every track in the game will have varying weather conditions. He said it’s unlikely rain will be added to Willow Springs since that location in real life has hardly any rain during the year.
