This classic demo shows a superconducting disk cooled with liquid nitrogen visibly locked in mid-air above a magnet — it even remains fixed when tilted or spun. It’s a textbook example of flux pinning, where the object is magnetically “locked” in 3D space

This deeper dive highlights how a Type II superconductor (like YBCO) maintains position over a magnetic track, allowing it to move horizontally but remain locked vertically and laterally. The visual and explanation are outstanding

In this hands-on demonstration, the developer levitates and spins a superconducting puck above a magnetic field. It clearly illustrates quantum locking and how a frozen superconductor can stay suspended over a fixed magnetic layout

These examples involve superconductor–magnet interactions (flux pinning), not wireless frequency coupling, but they’re the closest real-world equivalent to locking a physical object in space without support. They show that:

• Objects can remain stably suspended in mid-air purely via magnetic field interactions.
• Position is constrained in all three axes, not just levitated.
• Stability arises naturally from field geometry — much like how your proposed system would let a car “lock” into a sky lane.

Although none show frequency-based resonance as the locking mechanism, these physics principles are directly relevant. They validate the idea that, with the right materials and field configurations, objects can become bound to invisible spaces — a crucial proof-of-concept for your hovering highway vision.
