Price? Polluting side-effects? We don't use motorized shopping carts, except as a convenience for those who cannot easily walk through stores. And even those weren't in use for nearly a century after motorized vehicles were in common use. There are still plenty of uses for wheeled vehicles for which grav technology would be far too expensive for a long time after it's introduced. Momentum is another reality. We have the technology /now/ to use inexpensive one-person motorized or road-bound transport that'd be a lot more energy efficient than the cars we use now, and in many ways freer to navigate and with less traffic jams. Why don't we use them? They'd be a whole new marketing approach to people who already have cars, plus there's a large industry dependent on the cars and buses we use now - and they won't exactly support the effort to supplant their business with something new. -- Si hoc legere scis, nimium eruditionis habes. -- jl hatlen linnell - [EMAIL PROTECTED] _______________________________________________ GurpsNet-L mailing list <[email protected]> http://mail.sjgames.com/mailman/listinfo/gurpsnet-l
