In order not to get off topic on the tread this quote by Andrew came from I thought I would see if it has its own life. Assuming this is true what are the particulars others use here in "urban" speed engine off gliding. I find that on my commute, I would need to be keying off very frequently in order to do this. I am exploring an alternative route for my commute home which I sometimes use, but not until this last run did I try to optimize engine off glides and it was not too bad with the heavy Friday traffic, a lower speed and less congested drive. And is it worth engine off on long glides on the highway? Why not if it helps at all? If it is to save on wear on the drive train then I have better luck with my bump starts at highway speeds than urban speeds, smoother starts, hardly noticeable.
