At breakneck speed

Origin

The term 'breakneck' itself has been around since at least the late 17th century, vividly describing a fall or a place so dangerous it could literally break one's neck. But it wasn't until the exhilarating, and often terrifying, dawn of modern transportation—think steam trains hurtling across continents and early automobiles chugging along at unprecedented rates—that this potent word found its perfect partner in 'speed.' As humanity pushed the limits of velocity, the inherent danger of such rapid movement became palpable. The phrase 'at breakneck speed' thus emerged, a visceral warning wrapped in an observation, capturing the thrilling yet perilous essence of going unbelievably fast, fast enough to risk everything.
