Sitting in a cramped bar in Berlin one rainy evening, I overheard a heated debate among friends about the legality and ethics of impaired driving. One of them mentioned a device that could prevent a drunk person from starting a car. It piqued my curiosity: what exactly is this device that could potentially save lives? That moment pushed me to dig deeper into interlock devices, a technology that aims to combat drunk driving with both innovation and controversy.

The sun was setting on a chilly October evening in Berlin, casting long shadows on the bustling streets as I stepped into a small café to meet an old friend. He had recently exchanged his sports car for a more practical vehicle, but our conversation quickly turned to the increasing prevalence of car interlock devices after he shared a particularly unsettling experience from a colleague. As he sipped his espresso, he mentioned how costly it was to install and maintain such a device after a DUI charge. I realized that this was a topic not many consider until they face it directly, yet it raises important questions about responsibilities, costs, and safety.
