One chapter of the BMW Car Club of America recently sent out a message saying that they were banning any car that had advanced drivers aids such as Automatic Lane Assist and Automatic Braking from HPDE's. The folks at BMWCCA national headquarters got involved and they walked it back... for now.

A BMW Car Club Chapter Is Banning New Bimmers from its Trackdays

The "driver-aids" they are talking about are a much bigger issue than stuff like PSM, ABS etc. We've had some serious issues on track with newer Audi's that would brake on their own if they got too close to the car in front of them. Not fun mid turn. You can turn this off in some of the cars - but not sure about all the new cars that have this stuff.

I honestly think that if you can't disable these types of systems - you shouldn't be able to track that car. It become unpredictable in a situation which requires the predictability.
