Can somebody explain exactly what this system is supposed to do in the USA? I am not a big fan of Porsche saying it "includes the following functions depending on the country" without saying anything about the functions in the country the car is being sold! My daughter's CR-V blinks "BRAKE" when I seemingly am getting close to the car in front of me at a certain speed. I have not seen my Taycan indicate anything is amiss in similar situations. Any idea exactly what this does in the USA?
