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.
