...and usually these 64 bits are made from the MAC address of the interface linked to this IPv6 address (padded if 48 bits).

I think what you're looking for is RFC 4941, Privacy Extensions for Stateless Address Autoconfiguration in IPv6:

This document describes an extension to IPv6 stateless address autoconfiguration for interfaces whose interface identifier is derived from an IEEE identifier. Use of the extension causes nodes to generate global scope addresses from interface identifiers that change over time, even in cases where the interface contains an embedded IEEE identifier. Changing the interface identifier (and the global scope addresses generated from it) over time makes it more difficult for eavesdroppers and other information collectors to identify when different addresses used in different transactions actually correspond to the same node.

I just don't see people actually wanting this technology

Yes, I can't imagine anyone who'd rather be able to nap, read a book, or do anything other than staring at the bumper in front of them during a regular weekday commute.

You missed this other part of gstoddart's comment:

If I need to be paying attention every second in case the computer does something stupid (and need to be able to anticipate every point at which it could do something stupid), it will require as much or more attention as if I was driving anyway.

Maybe you shouldn't be commenting on Slashdot while napping, reading a book, or anything else...

Submission + - Queens WWIII Speech Revealed

Submitted by EzInKy
EzInKy writes: This BBC article provides details of the script the United Kingdom's Queen was to deliver in the event of a nuclear holocaust. The document, released by the government under the 30-year rule, was drawn up as part of a war-gaming exercise in the spring of 1983, working through potential scenarios. In it, the Queen was expected to urge the people of the United Kingdom to "pray" in the event of a nuclear war. Although it was only a simulation, the text of the Queen's address — written as if broadcast at midday on Friday 4 March 1983 — seeks to prepare the country for the ordeal of World War III.

The script reads: "Now this madness of war is once more spreading through the world and our brave country must again prepare itself to survive against great odds. I have never forgotten the sorrow and the pride I felt as my sister and I huddled around the nursery wireless set listening to my father's inspiring words on that fateful day in 1939. Not for a single moment did I imagine that this solemn and awful duty would one day fall to me. But whatever terrors lie in wait for us all, the qualities that have helped to keep our freedom intact twice already during this sad century will once more be our strength."

Just because your messages are accessible on a new device, it does not necessarily mean that your messages are readable or key is accessible by Apple. For instance, if the decryption key for iMessage were encrypted with your Apple ID password, then your key could be transferred around between devices, but Apple or the DEA would still have to brute-force/social engineer/whatever to get your password and decrypt the key. Whether or not it's actually set up that way...

It would make more sense to ask the students.

As a freshman physics major at a major research university (of Our Lady), I can reliably say that my peers and I find the best instructors are those who give traditional "chalk talks." Last semester I started going to a different chemistry section precisely because my old instructor simply rushed through some powerpoint slides and made some cryptic remarks, while the other professor wrote everything out on the chalkboard. As a general rule, professors who use Powerpoints just read off them, while professors who write on the board actually have something to say. Also, WebAssign sucks majorly. Nightly rants about WebAssign and online homework can be heard throughout the dorms.
