Nissan Leaf Prototype Becomes First Autonomous Car On Japanese Highways 140
cartechboy writes "As car manufacturers battle over futuristic announcements of when autonomous cars will (allegedly) be sold, they are also starting to more seriously put self-driving technology to the test. Earlier this week several Japanese dignitaries drove — make that rode along — as an autonomous Nissan Leaf prototype completed its first public highway test near Tokyo. The Nissan Leaf electric car successfully negotiated a section of the Sagami Expressway southwest of Tokyo, with a local Governor and Nissan Vice Chairman Toshiyuki Shiga onboard. The test drive reached speeds of 50 mph and took place entirely automatically, though it was carried out with the cooperation of local authorities, who no doubt cleared traffic to make the test a little easier. Nissan has already stated its intent to offer a fully autonomous car for sale by 2020."

I tend to think the lawsuit fears are overblown. In the U.S. alone, 35,000 people die each year due to human drivers, at a cost of about $200 billion annually, paid for by everyone's insurance. We seem to have no problem living with that.
If autonomous cars can cut that fatality rate to 3,500 or even 350 deaths a year, the savings will be so enormous that it will be cost-effective for the auto companies to partner with insurance companies and create a general fund to reimburse those people who may be injured due to an automation failure, regardless of fault. The federal government already uses this concept with the National Vaccine Injury Compensation Program. It provides no-fault reimbursement of vaccine-related injuries, because letting vaccine makers be sued out of business would result in more deaths and injures in the long run.
And keep in mind that accident rates will only continue to drop as the automation improves with time. Moore's Law is inexorable.

If the OnStar system is secured and only responds to a specific set of commands I see no "insanity". The whole CAN bus API would not be exposed through the OnStar API.

You are obviously not an embedded system engineer with mission critical design experience. The proper way to design a system like this is to have multiple processes running on at least two separate CPUs. The most powerful CPU computes the car's speed and path, and another process running on a separate CPU performs sanity checks on the results. If something is clearly wrong (like steering into oncoming traffic), then the backup program applies the brakes and pulls off the road. Bits can be flipped by cosmic rays, or whatever, and a system like this is designed to deal with that. This is standard critical system engineering. Then you put it on the test track, and throw all the crap you can at it: turn off sensors at random, put corrupt data on the bus, flip bits in memory, etc. Keep hammering it and fixing the problems until it can handle any failure as safely as possible.
