“Goodriver” is a car key which is combined with an alcohol detector. When a driver wants to drive a car, he needs to pass the alcohol test first by his car key, Goodriver, first. Otherwise, the key doesn’t stretch out. It can prevent drunken drivers from driving their car. Besides, if you are drunken, you can easily use “Goodriver” to call taxi for help. It can decrease possibility of traffic accidents.

此概念的設計將車鑰匙與酒精偵測的結合，並設計完整的酒精檢測機制與求助系統，讓使用者可以在無法駕車的狀況下使用Goodriver。在使用流程上，當駕駛者要駕車前，必須對著Goodriver鑰匙的酒精偵測位置吹氣，來感應駕駛者是否通過酒精程度，Goodriver的螢幕會顯示出你的酒精指數，若過關後鑰匙才會彈出，便可安全上路。倘若因喝酒而使酒精濃度過高超過標準，便會出現求助介面，可選擇向朋友求助或者呼叫計程車，來降低酒駕肇事的意外發生。
