[00:00:00]What happens when a car meets a bridge the size of a wire? Sounds [music] impossible, but engineers break it down step by step. First, if the car is too wide, it gets stuck underneath. So, the simplest [music] fix is reducing the wheel track. But when the bridge becomes half as wide, the problem returns. The car still gets trapped at the bottom.

[00:00:19]So, the wheels are brought closer [music] like a moving roller. But if the bridge shrinks to 1/3, a new issue appears, imbalance. The battery and structure shift [music] to one side and the car starts to tilt. To fix it, the battery is moved to the rear [music] center to rebalance weight. Now, the bridge is only 1/6 of its original [music] width. Wheel spacing is not enough anymore. You need support wheels and extendable arms to stabilize the vehicle, then [music] retract after crossing. But what if the bridge is fully circular? Simple support arms no longer work. You would need a balancing rod system like a tightrope walker, constantly correcting weight. [music] And if the bridge becomes a wire,
