Three things that are highly unlikely to happen within the next 20 years (be sure to read the disclaimer after the list before jumping in to comment):

1. SkyNet-style machine uprising or any similar “at which point the technology has became self-aware and decided to eliminate the humanity” event
2. Self-driving cars
3. George R.R. Martin finishing the “A Song of Ice and Fire” books

And now the disclaimer. By self-driving cars I mean the combination of technology and legislature that would give me the option, owned, leased or on-demand, to have a vehicle for myself and my family to get me from point A to point B at my time of choosing. The only mandatory condition is that it would not require me to pay any attention to what is happening during the trip.

If I am required – by technology or by law – to be able to take over the control of the vehicle at any point in time, that is not a self-driving car in my world. If the technology is only available on specific roads (highways, for example) or under very specific weather conditions, that is also not a self-driving car in my world.
