Malevolent or highly intelligent? :wink:

Sing to the well known spiritual tune:

Sometimes I feel like a driverless car
Sometimes I feel like a driverless car
Sometimes I feel like a driverless car
A long way from home.

Waymo or Volvo children

Here is an article that talks about driverless big rigs begin deployed in Texas, and I think they said next month.

I have seen multiple articles on this exact story. The article NOT linked talks about how they can't hire humans for the routes involved because it requires 22 hours of straight driving, then 22 hours of return trip - and nobody wants to do that. This is exactly what computers can do that humans should not be doing due to fatigue. Truck drivers are notorious for doing amphetamines to handle such long runs, so in an ancillary way, this project is preventing drug abuse!!! :D

Your example suggests it will soon be a lot easier to clock up food-miles, which is the very opposite of what most people feel we should be doing. I feel it might have been better to employ two drivers.

I must apologize. I do not understand what "to clock up food-miles" means.

It will be easier and cheaper to transport food longer distances. "Clock up" = add to the count. Speedometers and Odometers are sometimes referred to as clocks. If you drive a long distance you are "clocking up miles" on the odometer in your vehicle.

In Europe a vast amount of perishable food comes from the south of Spain and is trucked all over Europe. Tomatoes or strawberries, for example travel anywhere from 1,000-3,000km by truck before they get to the consumer. In the US the distances are probably even greater - California to Chicago/NY. Yes there is local produce but people have been trained to ignore seasons.

Depending on which statistic you prefer to believe, the average calorie we consume takes 8-15 calories of fossil fuel energy to produce. Transport is one of the components.

The AI "brain" of the self driving car is notoriously bad at handling situations it has never seen before. AI must be "trained" via simulations and real road miles. Their pattern recognition is still highly questionable. One of the recent headlines I posted about earlier was that the AI failed to recognize a woman pushing a bicycle across the street and made a decision to mow the "object" over, rather than slow/stop/swerve. The AI can recognize a bicycle, and a woman, but apparently, not a woman pushing a bicycle. This kind of thing is easy for humans. Obviously, not for AI.
Couldn't this be solved with traffic lights?
I see AI as not necessary to solve driverless car.
To me it is more about the brain of the engineers...
Or cost to avoid installing traffic lights everywhere...

I see AI as a current fashion and as such, people tend to overvalue it. I work in Advanced Control for Process Industries. Last year I went to a client to solve a chemical mixing problem. A startup company with specialists in AI used the whole year data and spent 3 months trying to tune an AI to control the process, with not too much success. I solved it in more or less a week only because I knew basic thermodynamics and how to install correctly a proper sensor.

But AI is great when used properly. I am now working with a self-learning MPC solution.

'The Self-Driving Car Is a Surveillance Tool:
In the coming age of autonomous vehicles, users may have to pay extra to keep their whereabouts private':

"..Moving forward, drivers who are shopping for a new car will probably face choices and trade-offs similar to those which today’s consumers face when shopping for smartphones. Companies including Apple charge a premium for phones that allegedly keep a user’s data away from governments and third-party vendors. (Some media outlets have investigated and arched an eyebrow at that premise, while others say privacy is Apple’s “best product.”) Other phones are cheaper but don’t promise to shield the user from surveillance.

In the future, if a driver wants a car that protects their privacy, “I think there might be a cost tradeoff,” Alvarez León says. “Which is how information companies operate. They provide services for free or at a very low cost, because they’re essentially being subsidized by the digital and personal information that they collect.”.."

Of course. Given the age we live in, why people might think this wouldn't be the case is a mystery to me. Some are happy with this, but why?

Why indeed. I struggle to understand why we're bothering with developing these toys.

Oh yes. The military.

Yes, just another tool for control of the many, by the Few.

My neighbor just bought a Tesla with the potential for full autonomy, and has been trying out its self driving features ON THE HIGHWAY, although he swears he only does this in places where traffic is light and speed is not high. When not driving it, he likes having it go up and down his driveway while he stands in his yard watching. An interesting choice for spending $55,000.

An article in today's New York Times quotes several people in the industry saying that previous estimates of the time required to get self-driving cars on the road were too optimistic. According to the article, "Despite High Hopes, Self-Driving Cars Are Way in the Future," "Ford and other companies say the industry overestimated the arrival of autonomous vehicles, which still struggle to anticipate what other drivers and pedestrians will do."

The problem is pedestrians, drivers, and vehicles behaving in wildly crazy and illegal ways that the software cannot anticipate. It was once thought that these situations would be rare, but studies now show that they are commonplace. Though the technology now allows the self-driving car to "see" everything around it, it cannot always predict what will happen next.
