Even the most optimistic estimates say that we won't see fully self-driving cars on the market much before 2020. The technological -- and legal -- obstacles that need to be overcome are significant, and working through all of the issues will take time.

But that isn't stopping automakers from bringing more and more pieces of the self-driving systems of the future to market now. This past week, Ford (NYSE:F) showed off a clever system that will park a car automatically after the driver gets out. Now, as Fool contributor John Rosevear explains in this video, Toyota (NYSE:TM) is showing off its own innovative new system -- in this case, an automated "co-pilot" that could make highway driving faster and safer in just a few years.
