That's a good question. When (if) we figure out how to practically travel at FTL speeds with a "warp drive", we might figure out the answer to this question too.
To be honest I think FTL is likelier than magical "sticks you to a fixed point in space relative to a rotating planet"-technology.
Sure you can do that with pushing air and a global positioning system, so if eventually we invent an eventual anti-gravity drive or something that may be used for the same thing. But wether such an entirely fictional device could be then made to (1) fit into a car sized vehicle and (2) be powered by whatever the most powerful mobile energy source is at that time and (3) become affordable to anyone outside of the 0.01% is another question.

I disagree. I'm no physicist, but given how gravity seems to be related to the structure of spacetime according to Einsteinian physics, and a lot of FTL ideas seem to center on the idea of "warping" spacetime, I suspect the two are highly related, and if FTL is possible at all, it'll be also related to artificial gravity.
