Most times that you pull up to a stop-light, you’ll notice a hexagon pattern in the pavement,sealed with tar.
What’s I’m the pavement is a very thin wire,and it wraps around the pattern at least 6 times. When current is passed through this wire,it creates an electromagnet in a simple normally closed configuration.
Vehicle detection.
The metal of an axle breaks the circuit,and tells the stop light that a vehicle is waiting. Drive through systems work the same way.
You could buy a cordless drill, And a handful of long screws …
Every stop light you approach at night, crack your door open and sink a screw into that hexagon pattern. The stop light will no longer work, it will cost the state thousands upon thousands to fix your evil laugh
