Well since we're on the topic of PDC, i would like to state that im not impressed with how early the beeping begins when im not even close to an object or car. I find this very annoying and misleading sometimes, espeically when im pulling out of a parking space. My front two sensors go nuts and start beeping very fast. It almost makes me feel like im gonna hit something beause the beep is so quick. Before my dad bought the X5, I was driving a chyrsler pacifica and the thing i liked about chyrslers sensors is that they had a digital display of how close you getting to an object. there would be a green, yellow and then red sections for when your about to hit something. I wish BMW had thought of that.
