For example, if you are driving a Scania or Volvo, you can’t always drive in manual mode, i.e. switch up and down over the retarder lever, what if you have to stop, is this a problem if you are driving for example in 7 gears and then stop at a red traffic light and after that stop first switch down into 2 gears. Or would it be better to quickly switch to automatic in such situations?
