The inherently chaotic event that exists in the otherwise predictable / trainable environment of driving a car is the unplanned / unmeasured disturbance. In control systems that are adaptive or self learning, the unplanned disturbance is the killer - a short duration, unpredictable event for which the system is unable to respond to within the control limits that have been defined through training, programming and/or adaptation. The response to an unplanned disturbance is often to default to an instruction that is very much human derived (ie. stop, exit gracefully, terminate instruction, wait until conditions return to controllable boundary conditions or freeze in place) which, depending on the disturbance, can be catastrophic. In our world, with humans behind the wheel, let's call the unplanned disturbance the "mistake". A tire blows, a load comes undone, an object falls out of or off of another vehicle (human, dog, watermelon, gas cylinder) etc.

The concern from my perspective (and I work directly with adaptive / learning control systems every day - fundamental models, adaptive neural type predictors, genetic algorithms etc. ) is the response to these short duration / short response time unplanned disturbances. The videos I've seen and the examples that I have reviewed don't deal with these very short timescale events and how to manage the response, which in many cases is an event dependent response. I would guess that the 1st dead person that results from the actions or inaction of self driving vehicles will put a major dent if not halt to the program. Humans may be fallible, but we are remarkably (infinitely?) more adaptive in combined conscious / subconscious responses than any computer is or will be in the near future in both appropriateness of response and the time scale of generating that response.

In the partially controlled environment (ie. there is no such thing as 100%) of a automated warehouse and distribution center, self driving works. In the partially controlled environment where ONLY self driving vehicles are present on the roadways, then again, this technology will likely succeed. The mixed environment with self driving co-mingled with humans (see "fallible" above) is not presently viable, and I don't think will be in the next decade or two, partially due to safety risk and partially due to management of these short timescale unplanned disturbances that can call for vastly different responses depending upon the specific situation at hand. In the flow of traffic we encounter the majority of the time, would agree that this may not be an issue to some (in 44 years of driving, I've been in 2 accidents, so I'll leave the risk assessment to the actuaries). But one death, and we'll see how high the knees jerk. And it will happen.

My 2 cents.

My black friend likes to talk about chicken and watermelon, and then we (group of friends/coworkers of varied races/nationalities/sexualities) ALWAYS laugh. Why do we always laugh? It's not fake or even nervous laughter -- he's just a goddamn funny dude; goes around doing a combination of Urkel and Denzel.

His story is the story of a black man that came to White/Asian Irvine California to teach the other races how to laugh -- and to pick up on hot Asian women near UCI. Sort of the opposite of the Hilarry Swank movie in all regards.

I've lived in areas of Orange County where it was very white and very racist, parts of the American "South" where it was very white and very racist, parts of Orange County where it was very hispanic and very racist, and parts of Orange County where it was so racially diverse no one really cared a goddamn what you look like, other than if you were a nerd or a jock.

Perception of racial issues depends almost entirely on where you live.

Taste is at least 50% psychology.
I once made a raspberry sorbet. Yes, it tasted very much like raspberry (because it was mostly raspberry) and if you work long enough with fruits, it's characteristic shade of red gives you a good hint what it is.
I like to let people taste stuff I make without telling them what they're eating. And then I ask them what they thought they ate. I gave several people that sorbet and out of 12 people, two or three gave me the correct answer what it was on the first try. Every red fruit you can imagine was mentioned by the others, one guy even told me it could be watermelon.
Another time I made a Cassis Panna Cotta (Cassis is french for black currant, you illiterate crouton). That stuff is purple like rain and Joker suits. We served it in a room that was lighted in blue and violet, like a Dario Argento movie. The Panna Cotta looked brown under the colored light. Some people thought they were eating something with chocolate in it.
In both examples I was dealing with people who made a living with selling and producing food.
That's how trustworthy your brain is when it comes to taste. Sometimes you can't tell raspberries from watermelons. And that's why the wine business is at least 50% bullshit.

Actually, it's for a reason, scientists now believe those seeds you have been joyfully spitting since you were a kid are actually the hardened remains of ant colonies.

These exotic ants immediately solidify the moment the shell of the watermelon is pierced and oxygen touches the interior of the fruit.

I'm glad Cheez-it's scored well - that's the only thing I like out of the whole list.
They should have had Sour-Patch Watermelon. I bet it would have scored 9.

Wrong! And who the hell puts watermelon in a bag?

This is the best way.
