It should be noted however that 2015 encountered by the DeLorean is presented as only one possible future. Some events such as Marty getting into an automobile accident in 1985 as well as him being fired from his office job in 2015 are explicitly shown to have been averted by the end of [[Back to the Future Part III|''Back to the Future Part III''.]] Whether the rest of 2015 was altered as a result remains to be seen. It is also possible that Doc and Marty's activities in [[1885]] had long-term effects that were still too subtle to be noticed when Marty returned to 1985, but which fanned out and caused significant historical changes between 1985 and 2015. Examples must remain purely hypothetical, but one could for instance imagine that the great-grandmother and great-grandfather of the person who would invent anti-gravity devices in the 1990s met on a train in [[1886]]. However, since the locomotive that would pull said train was stolen and destroyed by Marty and Doc already one year earlier, an entire family line faded from history. The inventor of anti-gravity devices was never born. Such hypothetical scenarios could explain why we currently seem to be headingfor a 2015 without hoverboards and flying cars.

*It is nearly 2015 in real life and yet there are no flying cars, auto-adjusting and auto-drying jackets, power-lacing shoes etc. From an "internal" perspective, it therefore seems clear that something has happened to significantly change history, possibly long-term butterfly effects fanning out from the subtle changes Marty and Doc caused in [[1955]] and [[1885]] after returning from 2015.

*Flying cars may be possible as Massachusetts-based company [http://en.wikipedia.org/wiki/Terrafugia Terrafugia] has invented the Transition, a car with collapsable wings capable of flight. They are expected to be marketed by next year. Another car, the TF-X will come out in [[2021]].

By this time in history, technology had progressed as much during the 30 years since 1985 as it had during the previous 30 years from 1955 to 1985. Electronics were in virtually everything from clothing to garbage cans to make them move, talk and/or make electronic noises.
Flying cars, once they were invented and perfected, had become so common that drivers no longer needed roads — except perhaps for short journeys. Skyways dominated the skies of central California and eventually the entire world. Cultural influences from other countries, particularly Japan, were more often seen in food and clothing.
Life was lived at a quicker pace than before, in evidence by the speed that people walked down the street, the time it took to cook dinner, and the swiftness of court trials.
Hill Valley underwent a period of gentrification, or revitalization of its downtown. With an increased concern for the environment, the Courthouse Square was landscaped with a large artificial lake (with the surrounding road having NO LANDING markings applied to dissuade drivers of flying cars from bringing their vehicles down near the lake), and businesses were brought back with the construction of an underground Courthouse Mall.

Marty poses as Marty Jr. and manages to change future history for the better by causing Griff and his gang to crash into the Hill County Courthouse, resulting in their being arrested.
The 47-year-old Marty, dared by Needles, illegally lets Needles scan his card, and subsequently gets fired by Mr. Fujitsu.
Thursday, October 22: Originally, Marty Jr. is tried, sentenced and convicted to 15 years in the state penetentary due to a robbery. After Marty changes history to save Marty Jr., Griff is sent to jail for wrecking the Courthouse.
Friday, October 23: Queen Diana visits Washington, D.C. according to the October 22, 2015 issue of USA Today (of course, in reality, the princess died in 1997).
Monday, October 26: Doc and Einstein arrive in the future (assuming they went exactly 30 years ahead from October 26, 1985).
Wednesday, October 28: Before Marty alters the course of future events, his daughter Marlene attempts to break her brother out of prison. She is sentenced to 20 years in jail.
Dates unknown: Doc spends an unknown amount of time in 2015 and later. While he is there, he outfits the time machine with a Mr. Fusion and a hover conversion, undergoes personal rejuvenation surgery, and learns as much as he can about Marty Jr.'s meeting with Griff on October 21. Eventually, Doc leaves for 1985 to pick up Marty and Jennifer.
Behind the scenes
Wednesday, October 7: The original year that Marty, Jennifer and Doc would travel to as opposed to the 21st.
↑When asking Doc why his 1931 counterpart couldn't have invented a hoverboard, Doc responds that they wouldn't be invented for another 84 years.
