Suppose an AI driver gets into a position where it has to hit either a young kid, or an old lady. Who does it hit?
Current sensors can't determine age. This isn't a problem because in an emergency situation most human drivers can't make that distinction either.
The best answer is: whichever human it would strike with the lowest impact energy. This minimizes the trauma, and it is a factor that normal drivers cannot consider consciously in an emergency.
Who is liable for the vehicular homicide?
As long as it's the manufacturer or your insurance company, who cares? Let the courts sort it out.
If self-driving cars are actually safer, insurance rates should drop anyway.
Can I tell it to go past the oil changes? Can I tell it that I want to drive on bald tires? Can I tell it I don't want it to phone home?
I don't understand what this has to do with self-driving cars.
Newer cars already have phone-home functionality. There are dash alerts for oil/tires/gas, but nothing shuts down.
I'd rather like to have one for maintenance purposes. I can tell it to drive to the shop after I get to work and pick me up afterward.
Can I tell my AI to speed? Can I tell it I'm in a hurry and will it respond by acceding to my wishes?
I assume you'll enjoy some personal liability if an accident happens in that situation.
If you really need to speed, choose a car that allows the operator to set the speed when they come to market.
if I don't like driving, why am I buying a car?
Maybe you like to come and go on your schedule, not whatever public transit dictates. Or maybe you'd like public transit, but it's not an option where you live and work. Maybe public transit is dirty, noisy, or otherwise unpleasant where you live.
So, there are a lot of reasons to want a car even if you don't want to drive one all the time.
