I can also confirm the rear assist works too !
My new GTI has this (as well as side assist and lane assist), and I've only had it a week and a couple of days ago, I was reversing off my driveway, which on the passenger side is surrounded by relatively high greenery. OK I was only going slow, but as the back end of my car nosed off the drive into the cul-de-sac, my next door neighbours 5 year old suddenly ran out behind the car chasing a ball. A saw him briefly in the rear view camera and the sensors immediately beeped, but in a split second before I could react, the car slammed on the brakes and stopped the car whilst I still had my foot on the accelerator pedal and certainly not on the brake pedal.
Pretty impressive really, although it was still a heart in the mouth moment, and it didn't stop him from getting a right boll*cking from his dad, who thanked me for being so careful
