During testing I started a session, when the car got to the track I enabled AI and let the car drive around for 8 laps. Whilst the car was still on track I disabled the AI (ctrl-I) and took control of the car. I found that when the control changes from AI to a real user, the tyre wear resets back to 0% wear (or 1 in the plugin value). After a lap of wearing out the tyres I changed back to AI and the tyre wear continued as normal. This is a bug, I hope the attached image helps to explain what I mean. Please let me know if you require more details. View attachment 8005
