new volvo?

I just saw a commerical for a new volvo that has a new feature to prevent collisions. It has like a warning beep when you get to close to the car ahead of you, and I think the same happpens for if you would back up and hit something. I wonder if they where trying to play off of he new Lexus that parallel parks itself? This definetly doesn't look as amazing, I think that the little beep warning would just be really annoying to me, and does it go off like whenever you get within like 10 ft of something or like 20ft, anyways i really dont think that this feature would make me want to buy the car at all. I fact I think it makes me want the Lexuz more.
