Saw this in the latest issue of AMCN It's real. Here's the first link that Google popped up on "Intelligent Speed Adaptation" http://www.publications.parliament.uk/pa/cm200102/cmselect/cmtlgr/557/55710.htm Great. I can see it now. Pick a gap. Go to overtake. Driver makes a slight judgement error (for whatever reason) and has to speed up to make the gap to get back in before some oncoming traffic/whatever. As he accelerates, the technology kicks in and slows him down, leaving him with nowhere to go because there's a car beside him, and the car that was behind him when he pulled out has since moved up to take his old spot. Instant head-on that was totally avoidable except that the choice/trust was removed from the driver that they could ever possibly use speed judiciously to avoid an accident. The article even goes on to control speed for "dangerous corners". Great. You enter a corner, rolling on the throttle, and suddenly the system kicks in and slows the bike down, forcing a front-end weight transfer that forces the motorcycle wide and correspondingly leaving the road.
