As I mentioned in another thread, I recently held off the AI in wet conditions on full wet tyres for the final 12-laps at China (full race distance - Driver Career - Grand Prix - SIM Rig - Cockpit View - PS5) to win by 5-seconds.
I found the AI behind me to be very challenging in the wet, ...but so they should be as I was in a (mid pack) Racing Bull, being hounded by superior Red Bull (Verstappen), and a Mercedes (Russell). However, I strictly maintained the racing line, I was patient on the throttle, I short-shifted, I used ERS whenever possible, and I was gentle with the brakes. ...and I maintained this concentration and discipline for lap after lap after lap.
It was a an extremely nerve-wracking final 12-laps at China on full wets, but it was also very satisfying as I eventually won by 5-seconds. This was MY most recent experience racing the AI in wet conditions, ...so yeah, I tested this too in racing conditions.
