Not sure if this has been mentioned but I know an upcoming update will include more options for hosts.
One option I would recommend would be a toggle to perhaps disable ‘wet races’. IMO they are totally pointless. However I appreciate there will be some that enjoy that sort of thing.
Another option for me would be to not use real world weather and create a mini weather system in game. Players can check a changing forecast and perhaps mini climates created to make wet races more interesting. For example races starting slightly wet(inters) getting to levels of needed wet tyres and then changing again. I know this happens every now and again however most wet races (and I have raced a few) tend to just have a constant water level thus no need to change tyres.
Plus obviously a toggle for ‘windmills’ and ‘flags’
