Nissan Leaf Prototype Becomes First Autonomous Car On Japanese Highways
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."
That's not a particularly difficult problem. An autonomous electric car could drop you off at the front door of your destination, then drive to a relatively distant parking lot where it can recharge using an automatic (robotic) charging station. Shortly before you're ready to leave, your would alert the car using your phone and it would pick you up at the front door.
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.
I don't see that as any different than someone not properly maintaining their manual car. I know lots of people that have been in accidents because of bad breaks or bawled tires.
people shouldn't be taking a break while driving much less bad ones! how can they even stand with crying tires? dude, you know some messed up people.
Anons need not reply. Questions end with a question mark.
As a side effect, this will finally, finally, FINALLY put an end to the dreaded find-a-parking-space-in-a-busy-city-on-Friday-night drill.
Self-driving cars can not only use remote parking lots, they can also make much better use of parking lot space. They are unoccupied when they self-park, so there is no need to leave room for people to exit. So they can park just an inch apart, and the absence of side mirrors will make that very close. Less space is needed for lanes, since the cars can steer optimally and coordinate their movements. Cars could park directly in front and behind each other, then when summoned by its owner, a car could signal for the blocking cars to move. The capacity of a parking lot can easily be doubled or tripled.
What if it suddenly veers into a wall or oncoming truck due to an incorrect or faulty instruction. Fuck autonomous!
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.
Car's CAN Bus is ring network with no authentication whatsoever and rudimentary priority system. If you can broadcast into it, then you can affect operation of the car in very drastic ways.
Much in the same way as the PCI bus on your computer has "no authentication whatsoever and rudimentary priority system". The bus does not need to be secured. The entry points to the bus need to be secures much in the same way as the Ethernet card provides secure access to the PCI bus.
Security researchers have taken control of in-auto networks by plugging hardware into the bus. You can do a lot to control a car if you can plug onto the diagnostic port and have a laptop sitting on the passenger seat. I think most people would notice that and be a bit suspicious. There has yet to be a wireless access into an unaltered in-auto system. If that starts to happen then worry.
Insanity is allowing things like Entertainment/Navigation/OnStar system access to it,
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. I used to work a a company that facilitated disabling vehicles and locking their doors (It was an application designed for an exotic car rental company. They wanted to be able to disable the vehicle if the vehicle was miss-used). Through our API those were the only commands available. There was no way a hacker could do anything else. The connection to the vehicle was authenticated and encrypted. Every entertainment system has authentication if it uses Bluetooth as authentication is built into the Bluetooth pairing protocol.
Authentication on the bus is not an issue; authentication at entry points is.
who no doubt cleared traffic to make the test a little easier.
Nothing in the article nor in the video backs up this assumption. So why was it in the summary? Having been to Japan, I doubt they would've done this, as the whole point of running the test on a public highway is to show it can cope with other traffic and real-life conditions, and making the test invalid in such a stupid and public way would mean quite a bit of lost face.

Yeah, obviously nobody has ever thought about that possibility before, so engineers have certainly not worked on making the system fault-tolerant.
