Toyota To Let People Ride In Self-Driving Prius 282
fergus07 writes "Toyota is to show an autonomous Prius at Tokyo Motor Show. Dubbed the Toyota AVOS (Automatic Vehicle Operation System), the car will be available for members of the public to take 'back seat' rides at the show, demonstrating first hand how the Prius can avoid obstacles, be summoned from a parking garage and park itself."

That's because 500 military personnel deaths would be a death rate of ~1:3000 (~1.5 million active personnel) while the driving deaths are ~1:7000 (about 240 million licensed drivers). So since one rate is more than double the other it's not surprising one gets more outrage.

No car I'm aware of has truly redundant o2 sensors.
The sensor(s) in the exhaust manifold (front o2 sensors) are for fuel trim. A failure or insane data in one or both causes the PCM to failover to preset maps and it begins basing injector duty cycle on the value in the maps that correspond to MAF/MAP, throttle angle, engine speed, etc. A failure in both sensors (assuming two banks) doesn't render the car undriveable.
It depends on vehicle manufacturer how a PCM handles a reasonbly responding sensor in one bank and a failed/insane sensor in the other. It may start using the values from the good bank to control how it fuels the failed bank OR simply go to the maps for both banks.
The rear o2 sensors ie., behind the catalytic converters, are used to determine if the catalytic converter is functioning properly. Failure or insane values from those sensors will trigger a check engine light and may (sometimes) cause the computer to go into a limp home mode. This is ostensibly to prevent some kind of engine damage, but my guess it's really a deterrent to basic tampering-gutting/removing of the catalytic converter, or to push the owner to repair a damaged/clogged converter.
Their position behind the catalytic converter renders them pretty useless in deciding fuel trim.

Mass transportation is much more realistic.
How would you like your Internet if all packets from all users are bundled into supermegapackets, each 10 Gb long, and then sent to all routers in the world, sequentially, on the odd chance that one byte out of those 10 Gb is addressed to that router? (The supermegapacket, like a bus, doesn't know where its passengers need to go.) You'd insert your packets when the supermegapacket goes by your home router; that'd be something like once per minute, or even more frequently in some special cases. Packets for you would disembark at the same time.
Well, of course if you think that one "delivery route" for the whole world is not enough then at certain routers (very few!) the supermegapacket can be taken apart, and its components can be repackaged into other supermegapackets that go to other routes. This only takes another minute per transfer - plenty fast, if you ask me.
Since that is also stupid, you will be reducing the size of supermegapackets more and more, and you will be increasing the number of routes until you arrive at the status quo.
Personal cars are popular because they offer 100% availability and because they offer point to point connection, at the shortest (or fastest) route that you control. They are also pretty cheap; bus tickets can be very expensive and you are typically charged per ride, not per day. So one day of shopping can result in spending more on the bus than on the goods.
