It was based on a true story, so I would hope so.

Do you find that things such as energy drinks work? Or do they not make a difference at all?

At the height of the ISS, time dilation isn't a problem. Time is off by .007 seconds after 6 months. Since the launch of the ISS, it's only off by around .3 seconds. ISS is 250 miles up (although this deviates a bit), and GPS satellites are at an altitude of 3,000 miles.

However, an important thing to note is that GPS satellites undergo time dilation due to general relativity (the further you are from a massive object, the faster time moves for you (relative to someone on that object)). Astronauts on the ISS experience time dilation due to special relativity (the faster you travel, the slower time moves for you relative to someone stationary).

Additional fun fact;; the orbital height at which special and general relativity cancel each other out is at an altitude of around 2000 miles.

Isn't the phrase "fall on deaf ears?

You said that the flying cars would have to be electric. But right now, developing a practical electric plane is incredibly difficult considering how bad of an energy density batteries have compared to regular fuel, no? Am I missing something crucial here, or are you guys hoping battery technology will have advanced far enough by 2025, or whatever year you have in mind, to make electric flying cars a viable option for transportation?
