Car Makers Explore EEG Headrests 77
mrtr writes "A number of car makers are looking at whether EEG devices built into headrests could prevent accidents by sensing when a driver is in danger of drifting off. The technology comes from Neurosky, which already makes commercial EEG units for use in gaming and market research. Other approaches, such as using cameras to spot drooping eyelids, have proven too unreliable so far. From the story: 'Fatigue causes more than 100,000 crashes and 40,000 injuries, and around 1,550 deaths, per year in the United States, according to the National Highway Traffic Safety Administration. Some studies suggest drowsiness is involved in 20 to 25 percent of all crashes on monotonous stretches of road.'"

But you could always go faster than you're going, there's no limit to that. You can always have arbitrarily high acceleration, assuming your car isn't so wimpy as to be limited by running out of fuel, or loss of structural integrity due to air resistance and friction, or having insufficient power to accelerate arbitrarily fast.

That is a very good idea. Not, of course, for reducing car crashes, but for accelerating the process of natural selection.

I believe a good portion of the Autobahn now has a speed limit. I was rather surprised in the area around Stuttgart in January this year.
Previously, I had been practically run off the road at 210 kph (left lane) while the right was moving at 100. Obviously, any sort of car problem (tire, suspension, etc.) would have been fatal with no place to go.
I found some unmarked areas around Stuttgart but the "default" seemed to be 100kph rather than unlimited. Very few places left without speed limits, at least in

Doesn't apply in general. There are plenty of Autobahns that do not impose speed limits. Also I found that most of the time when there is a speed limit on an Autobahn it actually makes sense for some reason! Contrary to that have a look at the A9 between, say, Bayreuth and the intersection to the A72. There's no speed limit most of the times. But there are 3 lanes for each direction (plus emergency lane) and the road is in good shape.

ALL of the Autobahn is limited to 130 kph - on SOME of it, you are allowed to exceed this, with the observation that you are absolutely guilty of any incident, if going faster than 130 (80.7 antiquated units per hour).
The rules relating to the layout and quality of the Autobahn are also more strict that anywhere, so before you apply observations about the Autobahn to any other stretch of road, first apply the rules.

I'd love it if we could get our speed limits up to 80MPH on the freeways here in California, and a minimum speed limit law for the fast lane.
I spent 3 hours on the road today, about half of it stuck behind a truck and an old guy, both doing 60MPH.
Honestly, experienced drivers know what the safe speed for a road is, and generally drive it - speed limits be damned.

Wait... the old guy was next to the truck for an hour and a half? That's illegal in most states. And most states do have minimum speeds on the interstates.
If you were on a two lane road, sixty is fast enough. There are people getting on and off, passing, etc. 80 on a 2 lane road is suicidal insanity, or stupid ignorance.

I do not agree with that assessment, simply based on pure experience, but assuming it holds true: Issue is not the experienced drivers - it is usually the in-experienced drivers, especially those who consider themselves competent drivers. They will not know when it is safe to go fast, and are too likely to go too fast.
Now, if auto-accidents were 100% solo-accidents, I'd be OK with this (see strange post above about natural selection), but since they will inflict damage on others, as society, we have to set

On a four or five line interstate, every single lane will be going 75MPH in Southern California. The DoT uses the guideline that 10% of drivers are crazy idiots, and set the speed limits on surface streets to the 90th percentile.
Except on Freeways, where they arbitrarily set much lower speed limits.

Of course, the problem with that is, a driver themself isn't able to judge if they're experienced enough... Total kilometers driven is only a guideline, some drivers will never be experienced enough no matter how many kilometers they've driven. Applies also to those who use miles.

Heck, I remember taking an Engineering Design class about 30yrs ago. where we explored several ideas to detect dozy drivers. Sensing brain activity (and I think we found ourselves zeroing in on alpha-wave activity) was one idea, and arguably the best idea we came up with. Even so, it wasn't ground-breaking 30yrs ago (although a good *implementation* may have been groundbreaking).
