Did anybody experience it in real life? Was anybody brave enough to push car to engage braking guard?

I had warning many times (bad habit to get close to the cars in front of me) but never experienced automatic braking.

Thanks!

Same. I've had the warning go off a few times, but I've never experienced the car autonomously braking itself yet. (If it indeed does/will)

Not on an S6, I haven't, but several times on my RS5. When it does happen it's quite humbling to realize how slow we humans are to react and how delayed the brake lights are of most cars. If traffic comes to an unexpected sudden stop, brake guard jams on the brakes before you even know that the driver in front of you just stumped on the brakes. I never realized how much of a delay there is between stepping on the brakes and the brakes lights lighting up and then there is the human reaction time. This stuff definitely makes for a lot less stressful driving.

Yes. Mainly when someone suddenly brakes and turns off a highway to a parking lot or such.
Also works nicely with the ever increasing number of people who don't repair their brake lights and thus have no working lights when they jam on their brakes. (The downside of removing state run safety inspections....that and the geniuses running bald tires. Sorry...pet peeves.)

thanks guys. Did car actually stop completely in your emergency situation?

No, it stopped braking after the car in front made its turn.
I'm not actually sure what would happen if the car in front just completely stopped....it may only stop itself entirely when driving in ACC mode.

Edit:
It looks like Brake Guard is only active ABOVE a certain speed...
"Audi braking guard is active at speeds above approximately 30 km/h and operates within the system limitations even when the adaptive cruise control is deactivated"
So once below that speed it would no longer stop you. But the idea is once the system jabs the brakes for you then the driver will be aware and take over braking properly. Also... "If you brake hard, the brake assist system helps you to achieve the optimum braking effect."

I've had it engage occasionally. Once or twice it saved my car if the speed differential was more than I expected. I get my most frequent false alarms from a car that's turning off; I know that the driver turning will not be in front of me anymore when I get to the spot he's in, so I don't slow down, but the car obviously can't read his turn signals like a human can, so the car freaks. I just jab the gas and the car realizes its mistake and I move on.

Interesting that it won't engage below a certain speed. That may have saved me a very unfortunate low-speed collision that caused almost no cosmetic damage to my car but kept it laid up in the body shop for 10 weeks last year.

On a semi-related note, I was driving my parents' 2015 Escalade ESV Platinum and backing into a parking spot at a restaurant - it flat-out refused to back further because it assumed I was going to hit something.

Never happened to me, but I let my brother drive it while I was in the front seat. He has a habit of tailgating, and when the car in front slowed for a turn, the S6 nailed the brakes. My poor brother was startled, as he had no idea what had just happened.

It was the first experience of automatic braking either of us had seen or experienced.
