A test of crashworthiness, usually involving the controlled crashing of a vehicle with dummies in place of human passengers.
Even the bad things are better than they used to be. Bad music, for instance, has gotten much briefer. Wagner's Ring Cycle takes four days to perform while "Mmm Mmm Mmm Mmm" by the Crash Test Dummies lasts little more than three minutes. P. J. O'Rourke
