Awesome update Reiza! However, I just want to report a bug regarding endurance racing pit stops. When swapping to the AI driver and changing tires, the tire wear state does not change. Visually the tires are being changed, and the compound changes, but wear stays the same as the previous set of tires. Changing tires without a driver swap, or swapping back to the player works fine. Unfortunately this kind of breaks endurance racing at the moment.
There are a number of things that don't get shown when the AI is driving your car and unfortunately tyre wear is one of them. The tyres have been changed and are actually new, it's just not shown on the HUD.
Are you sure? The wear indicator drops as they drive, and resets when they change tires, just not when you driver swap to them.
