Possible answer
Derek and Shirley looked at each other with wild panic in their eyes. The taxi was moving faster and faster, and “Rocky” seemed to be malfunctioning. “Slow down!” Derek shouted, but “Rocky” did not respond. The robot drove even faster than before and narrowly missed a car. Terrified, Derek grabbed his phone. With trembling fingers, he called the taxi company. “Hello ” Derek shouted into the phone, “our robot driver is having a breakdown and he’s completely out of control. We need help quickly!” “Don’t worry, sir,” came the calm reply. “Your taxi is also a driverless car. We have the authority to disable the robot driver. Let me switch your taxi to the driverless mode and get you to your destination safely.” The taxi immediately slowed down and continued as if nothing had happened, although its driver could be heard mumbling to himself, “... go wrong ... go wrong ...”
Possible answer
When they finally arrived at their hotel, Derek and Shirley quickly got out of the taxi, relieved and grateful to be alive. As they watched the taxi move away, they agreed that for the rest of the holiday, they would walk everywhere!
