they are still thinking about flying cars, NASA are currently running a development program to allow millions of "commuter aircraft" to be controled at the same time for that purpose, its a "proof of concept" thing, but they must be starting to think of it now the technology is getting there, you couldn`t trust millions of commuters to fly their aircars in safety in a busy city, but if they are controled via network?, still like to know what happens if your engine packs up though
why do they say Aliens are gonna be friendly?, surely the agressive ones wipe out the peaceloving ones, so all you have left out there are crazed flesh eating interstellar monsters.
