So this evening I found out what this feature is and it works! I was reversing off my mates drive onto a busy road and edging back to see traffic when suddenly the car beeps at me and slams on the brakes! So it works but maybe a touch on the sensitive side as in my opinion I was not that close to cars going past! Anyone else having fun with these features? Front assist has only beeped at me a couple of times and not helped me avoid a crash as I was manoeuvring etc at the time anyway.
