Hmm.

Imagine a big performance art project.

Imagine some artist takes a petri dish full of iron filings to a few of those magnets in the street and figures out how they’re polarized or if they’re coded in some way. Next imagine the artist going back to his or her art studio to assemble some magnets of a similar type. Last but not least, let’s imagine our artist getting some nice strong epoxy and gluing a whole bunch of those special magnets onto the roads. Perhaps in a pattern that spells something funny, like “Daisy, daisy, give me your answer, do.”

Then imagine a video camera linked to a live webcast. And then we can watch the silly busses go round and round in circles, whilst their passengers get on and off wondering what the boody hell is happening.

Hey be glad it’s only an art project, and not a terrorist group doing something awful like making them run into each other or drive into buildings. With ideas like driverless buses being passed off as green, when the only green in the picture is the money going into someone’s pocket after they fire all the bus drivers, we have to keep a sense of humour now, don’t we?

(DISCLAIMER: the above is not a suggestion or an incitement, but merely a humourous way of exposing a terrible security flaw in a terrible idea.)
