How To Make The Obvious Sound Scary
from the say-what-now? dept
We've had plenty of stories about how people over-relying on computers have made some pretty big mistakes. It's pretty natural. People expect computers to be right. It's obviously good to not blindly trust computers, but is it really so silly to expect an automation system to do what it's supposed to do? The Raw Feed points us to a fairly sensational claim that adaptive cruise control systems, designed to help drivers avoid accidents, can dull the driver's senses in a real emergency situation -- making it sound as though these "safety" systems can make driving more dangerous. However, the details point out how ridiculous this claim really is. What the researchers did was make the adaptive cruise control fail. Any driver, obviously, is expecting that it would work -- so why is it surprising, in any way, that they would react late? They expected the system to work, and it didn't. That's not "dulling the driver's senses," it's a system failure. The real issue is making sure that (a) these systems rarely fail or (b) when they do fail, the drivers are clearly and quickly alerted to that fact, so that they can override it with their own controls.

Remember the demo that turned into a three-merc-pileup because the system wouldn't work in the warehouse where they were demoing it...? seems to me the same system is just as likely to fail when you're going through a tunnel, or an underpass, or snow / hailstorms, or who-knows-what else. Can the system reliably predict conditions where it's going to fail like this? I don't think so.
I'd love a system like this, but I would never rely on it! I'd keep driving the car just as if the system wasn't installed, and hopefully the one or two times I'm distracted and _could_ have had an accident this thing will kick in and save my ass.

However, such redundant systems do raise the cost dramatically.

However, many people invoke cruise-control for the wrong reason. Personally, I activate it because holding my foot on the gas hurts on a long trip. Unfortunately, other people activate it because they expect a long, monotonous trip and want to relax. You simply can't activate cruise control to relax, as that's going to kill someone. Driving requires your full attention, with or without cruise control.
Having said that, and knowing that people WILL use cruise control for the wrong reasons, adaptive cruise control is a good thing. However, the original article's point about it "dulling the driver's senses" is a good one, if a little off the mark. As Mike mentions, the issue is not alertness, but reaction time due to the driver not expecting failure. The driver can be fully alert and looking for danger, but in order to detect failure of the adaptive cruise control system, the driver must witness it not slowing down, which will rob even the best driver of valuable reaction time.
I have mixed opinions. Given responsible drivers, redundant systems, and quality monitoring and alerting, it's a step forward. But given lazy drivers who use it when they would be best served by choosing not to drive at all, it's an accident waiting to happen.
I may not have passed the law that Belgium did were I in charge, but I won't argue with it either.

Re: The right reason?
Anything can be abused, though. It's not auto-pilot, and it won't react to an emergency situation--you'll have to apply your own brakes.

Besides, there are reasons we drive versus taking a bus, cab, train, etc. and that's so we can remain in control of what we do and where we go. If someone doesn't want to take responsibility for their driving at all times, they should use another form of transportation.

thats like saying...
disable someone's brakes and when they crash, say "see, they were driving too fast and assuming the brakes would stop them."

How about auto-steering?
So what happens if you're driving down one of those back roads where it's not maintained well and the lines are barely visible? Also, are they blinded by headlights from oncoming cars? Can they change lanes for you?
Just curious.
