I have thought about whether, or not, to make a reply since my opinion on the matter seems to be opposed, technically, to Saab's. I do not consider my *opinion* to be "drivel" and perhaps you should re-think your light use of a religious figure's name in international company. Where I live, if I uttered the word "Mohammed" in that way, I'd get shot ... seriously. I was not speaking technically, I was speaking morally. Who do the manufacturers think they are, making a decision about who to kill first? In fact, they are accepting (and adjusting for the fact) that a driver may fall asleep at the wheel of the car. In my city (Bradford, UK), I'm too busy avoiding race riots, car jackers, drug-crazed lunatics, joy-riders, thrill-seeking idiots and ram-raiders to fall asleep :) I do understand the benefits of rolling away from faster moving traffic in certain circumstances. But, I can *not* believe that manufacturers of cars can make a value decision about who to kill first in the event of a driver falling asleep at the wheel. They cannot predict where the car will be ... if it *is* on the motorway/freeway, all well and good if you're in the crawler lane, but what if the driver was in the outside lane - the car would drift uncontrolled across two other lanes of traffic and into the verge, rather than just hitting the central reservation barriers and waking the driver up :) If the car was on a long right-hand bend (or left-hand, whichever), this would happen anyway. If the car is in a city, suburb or even in the "country", the car will ride up on the pavement/sidewalk and potentially kill pedestrians. This is, honestly, the first I have heard of this. I have driven a number of cars of differing manufacturers and ages. The only car I have owned that drifted to the side of the road (left hand side in the UK), was my 1985 900i. I had the alignment and tracking set according to the specifications of a Saab of that age and it actually drifted even more to the left. When I got a new set of tyres, all Pirelli P4000, it drove (infact, "drives") in a perfectly forward position. All three Saabs (900 models) that I have owned (okay, they were all older models and I cannot comment on the 9-3 model) have driven perfectly forwards with equal wear tyres and correct wheel settings. I have driven brand new Vauxhall Vectras as well, which the modern Saab models are arguably based on - these do not drift at all. Why not? Why do Saab have a different opinion on the matter to Vauxhall, for essentially the same car? So, I stand corrected (or at least opposed to Saab's stance) - newer Saabs are made to drift to the side of the road. The original poster (Alan Zaza ) was asking if this was "normal" - I take it that it is for modern Saabs, although I do not think it should be. It does make me seriously think twice about buying a modern Saab. My question still stands: "If I have my wheels set to drive in a straight line, should I inform my insurance company that I have removed a manufacturer's factory standard safety feature?" You've had your say ... I've had mine - In all seriousness; happy Saabing, Paul 1985 900i 16V 1989 900 Turbo S http://pjgh.go.dyndns.org/saab/index.html
