A pen is writing autonomous driving. It’s a city with only autonomous taxis and no one else is driving a car. There are special bus stops but every human has a transponder with a bell for calling the taxi in there pockets too. Our main character is grandma Sabine. She wants to go to the doctors which is why she is clicking the button on the transponder to call the taxi. The taxi is arriving one minute later and is waiting outside the house. As soon as the taxi arrived, Sabines transponder started vibrating. Sabine says “wow, that was fast, how is that even possible? I really like that I can be super flexible without even driving a car myself. On top of that I do not have to worry about being to old for driving..”.
