I think as another customisation option the weather could be changed to use predefined random presets rather than relying on current weather.
~ coded, so eventually you could add radar and spotters that feedback updates.
~ each track could have countless presets and would just pick one from that selection (I’m thinking hundreds)
~ gold tiers could add their own presets to the random pile, setting temperature, rain and wind (not sure if wind is even used in iGP? If not, count that as another suggestion!) It would need restrictions on generation so the level didn’t change suddenly but fluidly over time.
~ gold tiers can share and select other peoples presets
