I was thinking they might install repeaters on the low cost airlines aircraft flying overhead (which they apparently want to compete with).
Rather than car drivers I was thinking the smaller villages/towns along the route may benefit too - like 15 seconds of wifi twice a day every day - then the government can say "how wonderful, x% more people on the internet thanks to wifi, aren't we clever").
They will, of course, have to switch off or re-route THAT train of Dubya's within range!!
