Today is officially the day Marty McFly arrives in our time. We know he will be surprised that it is way different to the 2015 he first visited in Back to the Future 2. Here a few of the things that are different from the 2015 Marty and Doc visited in the movies.
Hoverboards and Flying Cars
These two are, unfortunately, still not available. Flying cars are still only found in fiction and for hoverboards, no real or mainstream versions have ever been released. Though engineers have tried to create hoverboards using magnets, and a secondary magnetic field, none have been able to create a hoverboard that can glide on any surface.
On 2018 a flying car concept called T-FX may go on sale, but it is still very far from the flying cars shown on the movie.
