Danger Ride

(noun) "A perilous journey of over 20 miles in an untested vehicle in which the likelihood of loss of life, explosion, or, incarceration is higher than the expectation of safe arrival at the destination of said journey. The likelihood of mechanical failure alone does not constitute a danger ride unless the mechanical failure would certainly place the 'danger driver' where the aforementioned risks apply. The danger ride is often a moniker awarded posthumously."
