A growing number of vehicles are currently being offered with automated systems that make it easy for those who tend to freeze up when it comes time to parallel parking. But Ford is demonstrating an even more advanced system that can drop you off and then park itself.

The technology brings the motor vehicle one step closer to autonomous driving—a concept that several manufacturers promise to introduce by decade's end.
