I haven't read this whole thing, so forgive me if this has already been resolved. I can think of probably 6 or 7 times when I've avoided being in car accidents by speeding up (usually to avoid the yahoo who tried to change lanes directly into my car).
Not to mention, often times when say merging onto a freeway, you need to accelerate to get into the gap in traffic. What happens when you punch the gas to speed up and suddenly your car doesn't do anything and you broadside the traffic already on the freeway cause you expected your car to do what you told it to.
Bottom line, taking the power away from a cognitive, operator and giving it to an automated, blind system is NOT a good idea.
[edit: ok, now I've read the whole thing, and basically the situation that Avenger described with the semi accounts for about 90% of my examples. If the semi's doing 65 and you're doing 70 and you're towards the front of it when it starts to move over, your best bet is to accelerate to get in front (not to mention that doing so will put you into direct line of sight with the semi driver. On the other hand if you brake, you are staying out of view of the semi driver, and potentially putting yourself at risk to be rear ended by another driver behind you. And you'll still probably not be able to brake fast enough to avoid getting hit by the trailer anyway.]
[edit2: in fact, just in general, braking is FAR MORE DANGEROUS than accelerating, under any condition. You are waaaay more likely to lose control of your vehicle braking than you are accelerating. And you can see what's in front of you easier than what's behind you.]
If you choose not to decide, you still have made a choice.
Lassev: I guess there was something captivating in savagery, because I liked it.
