I bought this vehicle not long ago. I drove it on a rainy day with an average speed of 50mph. I hit the traction control to maximize traction control, but the vehicle started to act weird. First, It locked up my control wheel. then it started to roll left. I was driving alone so i assumed that there was more weight on the left and thats why it rolled left. The vehicle was designed to not let you place any control input to fix the left roll. I hit curve so hard that it almost took my life. I will never trust BMW traction control system again. If you own this vehicle and you live in a area where it rains a lot, I suggest you sell your BMW right a way. Its not worth it to risk your life for some beautiful interior designs.
