Nissan (NASDAQOTH:NSANY) promises that it will have more than one self-driving car on the market by 2020. While that may be the earliest you'll be able to drive a fully autonomous vehicle, the fact is that the technology is out there now – as Google (NASDAQ:GOOGL) has demonstrated with its vehicle (which you'll see in this video).

What's more, many cars you can buy today come equipped with features like lane assist, smart cruise control, and self-parking capabilities. Ford (NYSE:F), Toyota (NYSE:TM), and General Motors (NYSE:GM) will be among the automakers showing off self-driving features at the 2014 International CES in Las Vegas next week.

In this video, Rex Moore chats with the senior vice president of communications and strategic relationships at CES, Jeff Joseph, about the self-driving revolution – one of Rex's five tech trends investors must watch in 2014.
