Instructions: Simply write what the crusher is called in the Title, then describe what it does and how it should break the car here in the description.
A crusher with an emergency start. Basic conveyer speeds and a newer option: Lightning charges.
Here is how the lightning charge would work. Much like the conveyer speeds, you get a charge toggle that changes the rate of the strikes upon the tesla coil. Higher charges cause the coil to get struck more and the bolts to conduct to the car (or an unfortunate sap locked in with the crusher) more and less would cause more powerful but less frequent bolts to conduct to the car.
Do not touch the car after it was struck by lightning! You will die!
