Mike
I have seen a few times tyres being punctured during races. Same concept as running out of fuel.
As for reliability, I have been a victim to this as well, stretching to save parts at the end of the season. Retiring in Abu Dhabi on lap 53 out of 55 was heartbreaking, but in the end, this was my decision to make so I only have myself to blame. There is no need for random failures. In a competitive multiplayer environment, this is just a no go. This will kill off a lot of interest from managers, doesn't matter if you are seasoned or a rookie manager. How would you like it when you are heading for your first ever win as a rookie manager after a hard fought race only to let a 'random' mechanical failure prevent you from doing it with a handful of laps to go? These kind of things are useful in single player managers like Grand Prix Manager 2, Grand Prix World, Motorsport Manager etc when there is only AI involved.
I think there is some relation beetween "High temperature in live race", "Tyre Durability", "percentage of Tyre used in live race", "Car's reliability point", "Driver's Driving Style", "Driver's Attacking point", "Driver's Focus point", "Driver's Experience point" and "Driver's Composure point". So, do not take too much risk while your driver's skill/mental ratio and your car are not good enough. This will push the manager to think back to develop more durable car and better mental driver. Not only to developin the car's and driver's performance.
That was just what i though. I think it will make the game a little harder. But, anyway thankyou Mike. Have a great race.
