Chess or Go play by very defined sets of rules.
I am not certain that driving has such a defined rule set. Between human behavior and random events, there pretty much needs to be a reactive intelligence to be able to drive. Do we really want to make intelligent cars?
I’ve read where self-driving cars need to have human intervention every 3,000 to 90,000 miles, depending on how well they are programmed. How likely is it that a human being is going to be paying attention at the exact time he needs to intervene to prevent an accident? And even if he is paying attention at that moment, will he even have the skill to avoid the accident, since he likely only knows rudimentary driving skills? I can also see car manufacturers getting hit with huge liability lawsuits, since accidents would no longer be considered the drivers’ fault, but the fault of the manufacturer.
As I said before, I do not think self-driving cars are ready for prime-time.
Another issue is societal. As “smart” devices do more and more that humans used to be trained to do, humans just keep getting more stupid. The brain needs intellectual exercise just as much as muscles need physical exercise.
Stay on roads. Don’t run into people or objects (e.g. fallen trees) on roads. Don’t drive into tornadoes. Obey traffic laws. Follow other vehicles at safe distances. Don’t cut others off or otherwise drive in a way that other vehicles can’t reasonably react to safely. Takes turns, starts and stops at accelerations which vehicle occupants can reasonably acclimate to. Watch out for breaks, potholes and other defects in the road surface itself. Don’t drive faster than the visibility allows; if there is dust, fog or snow that reduces visibility, slow down before arriving in the reduced-visibility area. Watch for wet or icy patches of road, and slow down before arriving at them. Drive more slowly in snow or on ice. (Periodically do “brake checks” to ascertain safe braking rates under current conditions.) Look out for emergency vehicles, accidents, “unexplained brake lights”, signal or sign outages, riots or criminal attacks, and other non-usual conditions ahead of the vehicle and modify driving in light of the information. Pull over for emergency vehicles that are flashing their lights and/or activating their sirens. If there is an earthquake, stop, but, if there is a tsunami coming, renavigate and drive to high ground as rapidly as safely possible. Avoid routes that are known to have road hazards (washed out, avalanched, forest fire, etc) unless they aren’t completely blocked and are the only exits from a worse local situation (e.g. volcanic eruption).
