Firstly, I'm glad you and your family were not harmed. I do not in any way mean for this to be offensive or disrespectful, but would you still welcome self-driving cars had this incident been caused by a malfunctioning self-driving car as apposed to a reckless driver? My point is that self-driving cars lack the common sense that humans have. A human would immediately halt if they hear a child scream near their car, a car would continue moving along as if nothing is happening if it isn't designed or trained to detect screams. Until machines gain sensory and cognitive capabilities that exceed ours, and a working comprehension of human values, I maintain my stance regarding this issue.

> A human would immediately halt if they hear a child scream near their car, a car would continue moving along as if nothing is happening if it isn't designed or trained to detect screams. I don't know to what extent they use sound as an input (makes sense that they'd do, given horns). But for what I've seen, self-driving cars are much better than humans at detecting pedestrians in their vicinity, including cases in which a child can't actually be seen by a human driver and he happens not to be screaming.

  Machines are much better than humans at detecting pedestrians, but only in situations they are specifically designed or trained for. If a machine finds itself in an unfamiliar or unknown settings (or if its sensors fail in a way not accounted for in the design), it will fail catastrophically. A human will not. Hell, machines tend to fail even if the setting varies slightly from what they are designed for; just see the numerous ways self-driven machines failed recently for examples. Machines must gain sensory and cognitive capabilities that exceed ours and a working comprehension of human values for me to trust them.

A human will not. Fail catastrophically how? Worst-case scenario for a well-designed car in a situation it can't understand is to park itself and refuse to go on unassisted. There's no neeed for general AI to implement such a behavior.

All these are false positives. What I object to are the costs of false negatives; A situation where the car mis-recognizes an abnormal situation as normal, and then proceeds to act on it's failed understanding. The Tesla is a good example of this; the car failed to recognize the obstacle in front of it and acted accordingly (namely, crashing full speed into the object). Regardless of the underlying reason, a machine did not recognize it was in an unknown setting, and thus failed to react correctly. A human, on the other hand, notices, and will generally use what capabilities they possess to at least attempt to handle the situation safely. I do acknowledge that self-driving cars will likely be statistically safer, but until these cars completely exceed the all the capabilities of human drivers, I refuse to trust them. Regardless of statistics.

        >The Tesla is a good example of this A car without LIDAR, only relying on camera. >A human, on the other hand, notices The camera didn't even doubt that there wasn't an obstacle in its path due to how it camouflaged against the background. I doubt the human would've seen it. And you're speaking of a prototype hacked on a car barely prepared for self-driving situations (again, no LIDAR and early iteration) and being used improperly. You're not making a good argument here.

> would you still welcome self-driving cars had this incident been caused by a malfunctioning self-driving car as apposed to a reckless driver Absolutely yes. Because if a malfunctioning self-driving car will cause an accident, this will be treated as a bug and fixed. Updates will be rolled out to every self-driving car, making it very unlikely the same accident will ever happen again. Issues with human drivers, on the other hand, cannot be easily fixed with an update. Human drivers repeat the same "malfunctions" again and again (like driving too fast, driving while being drunk, not paying enough attention to the situation, ...).
