Driving: Horsepower.
Flying: Air Resistance.
Diving: Pressure.
Space: Gravity.
All three of those affect speed. So, we'll focus more on speed than anything else. By 2050, we should reach 900 MPH with driving, commercial jets will replace airplanes and
possibly go Mach 2, Diving will not be mastered until about 2100, but will allow for anti-pressure mechanisms and magnetic propulsion. As for space, it depends on when we continue the Space Age. 20 years after restarting it, the Space Station seen in the movie Zenon should be POSSIBLE, even if not built + sent. It'll most likely be situated as a midpoint between us and Mars - which will be our focus due to its insane potential for being terraformed.
Also, Space Age will start again due to aid by Google and its alliance with the third parties focusing on space travel today on the Isle of Mann.
Driving COULD end up being like in Total Recall (2012) where magnetic propulsion IS allowed for hovering, but requires "magnetic locking" on specific roads - because of this, cars most likely would need the ability to change to wheel form on non-rail roads. However, I still believe horsepower will be the focus.
Flying will require upgrades to vehicle parts, for Mach use. It'll also mean the end of "no phones" policies as technology will force commercial airlines to accept use of tech on the plane. And no, magnetic fields of your devices don't affect the plane's controls - that's a lie.
Diving would be allowed mainly for marine science only, due to insane costs. In other words, use of these vehicles for pleasure and war would cost too much - so a "borrowing" system based on necessity would exist.
While I DO agree with the Jonah Brothers that underwater cities could exist in the year 3000, I don't see that starting to be a thing until atleast 2300.

We CAN "warp" already. We used the finding as to why "time travel is actually impossible" - something about matter being ripped apart if we use the wormhole we found or something? Something like that... Anyway, we used that info to figure out how to warp things. Problem is, we NEED gates - the matter has to pass through objects on the way there, and the recompilation of living things has ethical issues when you realize that "people matter" will be crossing other "people matter". Until we make the Stargates, it aint happenin'.
