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.

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.
