While the Lexus Hoverboard currently requires a magnetic track in order to operate
The repulsorlift technology does not. It’s worth noting that the planet itself produces its own powerful magnetic field, which is one of the reasons life has been able to develop here. Earth’s magnetic field protects us from deadly cosmic radiation that would otherwise prevent life from evolving.
We can be certain that something similar to the Lexus Hoverboard’s technology will emerge in the future, allowing us to interact with the planet’s own magnetic field rather than a magnetic track. Who knows what strange and wonderful technologies may appear in the near future? But it would be a revolutionary one, potentially removing the problem of exiting Earth’s atmosphere from anything approaching how a Star Destroyer handles it.
