You are right, this video only hints at this at the end but if you read closely the specs Skoda seems to promise exactly that - automatic breaking to avoid collision. Here is a blurb on their Front Assistant feature (http://www.euroncap.com/en/ratings-rewards/euro-ncap-advance...)
"Skoda Front Assistant is a system designed to help avoid or to mitigate accidents into the rear of preceding traffic. A long-range radar, positioned at the front of the car, can detect vehicles up to 80m ahead which the car is likely to hit unless action is taken."
Keep in mind, Skoda is not an upscale brand, they are on the budget end of things. The VW and Audi models might/should have better systems.
The new Peugeot 308 also offers a 'Emergency Collision Autonomous Braking System' (http://www.peugeot.co.uk/showroom/308/5-door/p=safety/) but on closer look this is actually 'an automatic brake application to reduce speed by a maximum of 12mph to reduce the severity of impact'. Much less useful, but at least moving in the right direction.
