That stop assistance can be a curse too. I would never want that as a feature of any car I drive. Reason...
A few years ago we went to a Bonnie Rait Concert right in the heart of Oakland on a Friday night. HUGE mistake. It was late when we got out of the show, and as we were making our way to the highway, this a-hole decides he is going to try and step out in the street to make us stop. Doesn't take a great deal of imagination to figure out why he wanted us to stop. I looked at my Wife and said "hold on". She knew exactly what I was going to do. Yes, I nailed the accelerator. At that point, @sshole had two choices; jump out of the way or die. He jumped out of the way and we kept on going.
Now, with this assisted stop bullsh!t, we would have been either robbed, killed or both. So thanks but no thanks. I will never have a car or have crap in my car that takes me out of control. Never.
