One of the stories featured in the next edition of the Computers in Classrooms newsletter is about driverless cars. This is at once both exciting and terrifying, so I think it will be interesting to look at under the topic heading 'technology in society'.
The concept is not new, of course. Work has been going on in this area for a few decades. Here in London, England, we have the Dockland Light Rail, which can do its thing with no driver.
So, in case you're intending to read that article, here is a video I made back in 2006 about the Dockland Light Rail. Think of it as an advance organiser, cf Ausubel. (If you're not familiar with that idea, take a few minutes to go through the SlideShare presentation below.)
