Abstract
A method of disabling a motor vehicle, comprising the steps of, firstly, providing an apparatus for disabling a motor vehicle which includes a plinth-like base small enough to fit in the palm of a person's hand. The base has a first substantially planar surface and a second substantially planar surface. At least one spike receiving aperture is provided in the first planar surface. At least one hollow tubular spike is removably secured in the at least one spike receiving aperture. The spike protrudes from the first planar surface at an angle of between 55 and 90 degrees. Secondly, positioning the plinth-like base under a tire of a motor vehicle with the at least one spike pointing toward the tire, such that upon the tire rolling over the plinth-like base, the at least one hollow tubular spike is transferred from the base to the tire, puncturing the tire and thereby serving as a conduit for the gradual escape of air to deflate the tire.
