Well, there would be nothing denying your "right to move about freely". Just the method of doing so.

But on the main point I didn't say anything about the ability of computers at the time...just that it could be cost prohibitive and create unnecessarily complex and more likely to act incorrectly code that could have been omitted otherwise. Nothing is more risky than dragging around unused and often forgotten code. It sounds like a rather easy way to introduce holes.

It wouldn't really be about the length of code. It would be an impossibility in most cases due to risk assessment. For example, if you are on a 3 lane highway and the two cars in the outside lanes are computer controlled and the car in the inside lane is human controlled, if the human starts drifting over into the other lane the computer will go through risk assessment.

Sure the computer in the next lane will detect it and move over, then the computer in the far outside lane will detect the movement, but if you are in the far outside lane and farther outside is a concrete divider, which is riskier, taking a side collision from a car or slamming into a concrete divider to prevent it? Either way the human caused an accident that the computer couldn't prevent.

There is too much personal bias for you to see our point of view. Just like we will only see a small degree of yours no matter how empathetic we are. This is the problem with society these days. Compromise has been compromised. No longer is it OK for both sides to be somewhat unhappy and not get everything they wanted but still worked out something that generally benefits everyone; instead it has come to a world in which if you (or I) don't get every single scrap of what we want then it wasn't a compromise it was someone working against us. People to be honest are bad code.

But the horse example is pretty accurate...horses have for the most part been removed from any interaction with the road and people who like riding them have to find places to do so. Why is it OK for them to be disenfranchised that way and yet not people who feel the need to drive their own cars? Horses in the early days of the car actually created a hazard that would make driving a car risky (IE manure on the roads introduces slicks that could make cars go out of control). They had to go or else we'd be dealing with the stench of manure and pollution from cars along with various other conditions. But they weren't outlawed to where you could never ride a horse anywhere. The same should happen to human driven cars.

The google car has a semblance of an AI, and one of the people speaking about it in their videos is a Stanford AI professor (havent looked to see if he does research).

even if it was a slew of if-then statements it's very robust. With more development and research its more than likely to succeed.

ITT: Everyone thinks they drive better than The Stig.




This tech is aimed for those 16 year olds who text while driving and drive a full-size pickup truck because "it's safer" when they really mean to say "I'd rather just kill the other guy while i'm too distracted to drive."

It's for the old people with failing brains and vision, or the guy with road rage who cuts you off because you looked at him. Or the chick who drives 90MPH with her knees because she's putting on makeup.


While I think I drive better than most (see top line) I can't wait to get all these idiots off the road where they can kill me.

A co-worker and i were just discussing this.

It would depend on what the computer is looking for. If all it is doing is scanning the area and doing object detection (and keeping you on the road) I don't think it would be above current tech. If it saw a car on a collision course, be it manual or computer controlled, it would adjust course to miss it or take a standard set of steps to hopefully reduce the severity of the impact to the occupants of the car. If cars were networked to all the other cars in the local area then they all could act as one and hopefully avoid it. As long as the the offending car wasn't swerving all over the place and had a predictable speed and heading it should be one simple calculation to avoid it...though this one calculation may need to be ran on every object in the area many times a second...but have you seen some of the super pi scores on CPUs these days?

Basically the short of it is that when an object the mass and size of a car is involved...there isn't a lot of variables to consider over a time period of a few seconds. It could only change speed so much as well as likely not change its direction much. Throw in a computer that could predict the car's location about 10,000 times a second and I think we'd all be surprised at how few accidents would happen even at high speeds in heavy traffic.

Another thing we talked about was that we don't think this would change too much with DUIs and such...just like in an airplane with auto-pilot. There must always be a capable person "in control" of the vehicle. So we kind scrapped the idea of actually working from our cars or not having to take taxis home from the bar. Heck, even trains need to have drivers. If anything could be 100% automated you'd think a train could. Well, there are a few trains that are...but not many.

I have a better solution to improve road safety rather than useless nanny computer systems.

A giant spike on the steering wheel, that sits only a few inches from your face. If you crash, you are instantly killed. If you bump in to someone, you are instantly killed. If you go too fast over a speed bump, you are instantly killed. If someone hits you, you are instantly killed.

Roads now "safe."

It does not have to account for human behavior at all. It just has to model objects and possible behaviors.

i.e. A car is just box moving at X speed. The most it can drift/turn in X time is X amount. Therefore, keep X distance away.

Or that car over there is drifting at 30% higher that nominal values. Provide for extra distance.

It's for people who have better things to do... I rather read, play games, sleep, eat, work, talk/play with my kids rather than drive (and so would most people).

Even if you found driving enjoyable, would you rather be doing something else? Economic cost.

Oh, I see your point of view just fine. I just don't agree with it. Further, for the past couple posts, I'm looking at things from a point of view ... a Constitutional (specifically a 10th Amendment) point of view.

Now if you want to say that we will have this technology and magically this very divided country will magically pass a new Constitutional Amendment to get around all the legal issues, then fine. I just don't see it happening in my lifetime. Forget the technology side of things, this country is just WAY too polarized to pass a Constitutional Amendment that would strike at the very heart of how our society works. Thus, for the very foreseeable future, the notion of "banning humans from driving" will be, at BEST, on a state by state issue.
