Traffic congestion is indeed a significant draw for autodrive cars.
Another solution for that would be teaching people to ****ing merge properly.Comment

For some reason, I doubt that would get you to where you're trying to go any quicker.I came upon a barroom full of bad Salon pictures in which men with hats on the backs of their heads were wolfing food from a counter. It was the institution of the "free lunch" I had struck. You paid for a drink and got as much as you wanted to eat. For something less than a rupee a day a man can feed himself sumptuously in San Francisco, even though he be a bankrupt. Remember this if ever you are stranded in these parts. ~ Rudyard Kipling, 1891Comment

How do we know when is the right time? The Grand Challenge was a real eye opener to me. It's a small billions solution to a huge billions problem. I guess I imagined there to be a lot of exotic technology required.Comment

DanS you COmmie!!
But I agree, it's horrible that we accept these traffic accidents without question.
Our system can be vastly improved, the saftey features built into cars over the last 50 years are nothing but unispired and we have the capability to change this to make the roads safer for everyone.We the people are the rightful masters of both Congress and the courts, not to overthrow the Constitution but to overthrow the men who pervert the Constitution. - Abraham LincolnComment

That's true, but again I have the sense that the technology required already has huge capacity. Compare to hybrid technology (which I like), which requires batteries that are not manufactured in quantity. Autodrive is mostly a computing problem, and we have huge silicon capacity.I came upon a barroom full of bad Salon pictures in which men with hats on the backs of their heads were wolfing food from a counter.

Autodrive is not mostly a computing problem.
Once you get the computing problem out of the way the problem is going to be in the cost of the high-tech sensors and precision actuators you need to litter the vehicle with.12-17-10 Mohamed Bouazizi NEVER FORGET

I sense you're wrong. Hybrid technology is understood, and represents an engineering problem. Autodrive is an artificial intelligence problem, not a computing problem, and is largely theoretical.Comment

It seems that the sensors are less high tech than I imagined, since a low budget, essentially home garage-built vehicle completed the Grand Challenge (it only took the team a year to do). And the actuators need not be extremely precise. We've had anti-lock brakes for a couple of decades.Originally posted by KrazyHorse

The most expensive part would probably be the drive-by-wire technology. But that's going to be instituted anyway in the next several years, regardless of autodrive.Last edited by DanS; October 17, 2005, 01:49.I came upon a barroom full of bad Salon pictures in which men with hats on the backs of their heads were wolfing food from a counter.

Anti-lock brakes are simple as ****, and even they add hundreds to the cost of a car.
Steering actuators are going to need to be far more complex. Now add in the price of 4-way radar, visual cameras to sense the edge of the roadway, etc12-17-10 Mohamed Bouazizi NEVER FORGET

All antilock brakes do is sense a sudden drop in force caused by transition from static to kinetic friction and release brake pressure, then reapply.
Repeat several times a second.
It's a simple on/off switch.12-17-10 Mohamed Bouazizi NEVER FORGET

I cross-edited you.
Steering actuators come "free" with drive-by-wire, as the Stanford team used in the Grand Challenge. Visual acquisition is really, extremely damn cheap (trust me on this, the chips cost $5 apiece in qty, that's why all those ****ty webcams proliferate; even 1920x1080 resolutions are ~ $12 apiece in qty; 60 hertz). 4-way radar is something I don't know a whole lot about, admittedly. Might be expensive. Might be silicon and damn cheap, just like sonar. I suspect laser rangefinding is very cheap, considering all of the silicon that's been printed for other, low cost products.Last edited by DanS; October 17, 2005, 02:09.I came upon a barroom full of bad Salon pictures in which men with hats on the backs of their heads were wolfing food from a counter.
