I started ACC Career mode and I'm in the race, the engineer says that I have to do a pit stop with driver swap however the driver swap option is greyed out, I cannot click on it at all (I have the option to change tyres or not). I restarted the race several times however the option is still grey. Please help me how to get it work, thanks. Also I always get speeding in pitlane penalty when I'm done with the pit stop (where I can't swap drivers). Edit: So apparently you don't need to do driver swaps and the race engineer lies. Also I've figured out why I got the penalty in the first place because after the pit procedure the pit limiter switches to off automatically, which is weird.
