So just ran a race at Silverstone in my career with Mclaren. I am in the first season with minimal upgrades to the car. Quailfied P 15. The race started dry but was forecasted to start raining mid to late race (I only race 25% races. Dont have the time for much more). So I decided to start the race on a harder compound, betting that it was going to start raining later, and planned on trying to hold out until I had to come in for Inters. This EASILY allowed me to exploit the AI since they all started on softer compounds, came in for the mandatory harder compound, then about a lap later the whole field pitted again for inters as it had indeed started raining. This allowed me to get a 2nd place finish with a car that should consider anything in the top 12 or 15 a win. I pitted once...everyone else pitted twice.
I hope they can address the dimwitted AI in regards to wet weather strategy in 2018.
