Future Technologies: "Burning Chrome" by William Gibson

Hippies have known about these dangerous technologies for a long time, and the state cracks down hard on them, and not entirely without good reason either. The world cannot run (for long anyway) on raves and drugs and loud music, any fool can see that. There is also a false economy in these supposedly 'efficient' economies, because if you run a sustainable event and people attend your event in a car, you can wave goodbye to any benefits you might have yielded from the technology itself. The ubiquity of the car, and all the other rampant wasteful consumerism which often surrounds an event, cripples your efforts right from the off. This thinking is very much in a fledgling stage and has a long way to develop before it could be said to be anything more than purely experimental, but experiment we must.
