"Roads? Where we're going we don't need roads!" is from which major movie?

This line is from the 1985 film Back to the Future, directed by Robert Zemeckis. The words are said by Dr. Emmett Brown to Marty McFly, a small-town California teen, who is a high school student that finds adventure along with Dr. Brown, using a DeLorean time machine to time travel to different periods in the history of Hill Valley, California.

Here the reference to something over and above the actual use of roads (streets). Literally, the use of any road is not directly meant. Used in the context of the film, the line makes one think that the specific meaning is truly about something else. It is about something that will be hard for people to accept as possible.

This movie shows us and refers to the virtue or ability of taking one's ideas and making them real. Words and concepts, in this case, become actions that make things happen. No unnecessary directions or fears can cause Marty and Dr. Brown to deviate from going to a place (in whatever year) and doing what is skillfully needed to handle a watershed crisis.
