1/150 scale Car System in which the car runs along wires under the road

The 1/150 scale car runs along wire embedded underneath the road.
Start, stop, headlights, and turn signals are controlled by remote control.
The steering moves along embedded wires, so the car can only run on a set route.

The battery is charged by inserting a small self-made charging pin into a hole on the bottom of the car.
The dimensions of the car body are 24.5mm(L)x11.4mm(W)x10.5mm(H), the wheelbase is 16.5mm, and the outer diameter of the tire is 4.0mm.
