[SpiraMirabilis]

I can see flying cars by 2057. I doubt they'd be much controlled by the soccer-moms and more like UAVs with people inside though. Look at the Global Hawk, a military project that can taxi out, take off do its mission, fly back to base, land and taxi into a hangar with one click of a mouse. 50 years to advance that kind of technology -- not that difficult to contemplate at all. Thankfully I'll be retired by then!
