It is very common in Europe, only now is it starting to make its way over to NA. Whats interesting though is that there actually is not alot of fuel saving going on from stop start tech. Hyundai has come out and said they are abandoning stop start tech becasue they are having trouble showing a 1 mpg efficiency gain.What I was trying to say is that since I've used it, I didn't find it annoying at all. In fact I didn't even notice I was driving a car that had it until I noticed the tachometer went to zero when I stopped and the engine turned on when I pressed the clutch. There was no delay. I'm going to Germany again in less than a month and I'll be renting a car again. This time I will look and see if the car I get has the same feature. I think this must be pretty common in Europe because over ten years ago when I went to Switzerland for the first time I noticed drivers shut their cars off at red lights and railroad crossings.
