Special permit 17 years driving without accompanying person

Hello together, I am 17 years old and do a training as a driver, so I have to change my job every few days. Today in Cologne tomorrow in Oberhausen etc.. It is sometimes not possible to reach the places without taxi, because there is no possibility to drive by public transport. Therefore I wanted to ask you if you see a possibility to get a special permit for driving without escorting. I did get with how often the topic but no example like mine was found yet. MfG Simon 1997
