It comes from the excellent YouTube channel Engineering Explained and it explains (duh) not just how you do it, but what's happening inside your gearbox when you blip that throttle and match revs. Like its other driving-related videos – the double-clutch video is really good, too – EE takes a step-by-step approach to heel-and-toe downshifting, making it easy to follow along and picture each individual step. More than that, though, it actually explains the benefit of heeling and toeing (although it fails to point out the biggest and most important reason to do it – because it's damn good fun). After watching it, you should be equipped to hit the road and start practicing.
