“Partly, this automotive legerdemain is thanks to the same trick that makes much AI appear to be smarter than it really is: having a backstage pass to oodles of data. What autonomous vehicles lack in complex judgement, they make up with undivided attention processing unobstructed 360° vision and LIDAR 3-D environment mapping. If you had that data pouring into your brain you’d be the safest driver on the planet.”
But we are not capable of handling all of the data described above pouring into our brain. The flow of sensory data from our sight, hearing, smell, taste and feel are tailored via evolution to match what our brain is capable of handling. AIs will be nowhere as limited as we are, with the perfect example being the AI cars you describe so well.
I’m not sure that the bandwidth of a Tesla’s sensors is that much greater than what is available to the external senses of a human being when you add in what’s available through all the nerve endings in the skin. Humans make that work for them through the Reticular Formation, part of the brain that decides what sensory input we will pay attention to. Meditators run the Reticular Formation through calisthenics.
However, the point I was making was that the human brain behind a driving wheel does not have available to it the sensors that let a Tesla see through fog or the precise ranging data that maps the environment. If you could see as much of the road as its cameras, you’d certainly be safer than a human driver without those aids. The self-driving car with its ability to focus on many areas at once and never get tired has the potential to do even better, which is why people are talking seriously about saving half a million lives a year.
