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.
Basically an angled speed test but the floor to the way down is very slippery (and white colored to indicate that its either covered with snow or made of ice) and therefore have no control over the trajectory of the vehicle. on the slope there could be polygonal objects (like wedges) that you can hit on the way down that break down your car before you hit the bottom, if possible make it so the bottom of the crusher dosent damage your vehicle as much as the shapes on the way down
for the availability of the crusher ill let the devs decide
