The vehicle starts to move when you move the cursor out of the stop zone. Notice how the caption bar changes from Driving: PAUSED to Driving: Forwards or Driving: Reverse to reflect the direction of travel. Click the left button again when you wish to pause.
A dotted line representing the current wheel angle is displayed on the overlay. If you have steering rate limits enabled you may notice that it lags behind the requested steering angle represented by the cursor.
