2. The time difference between changing from manual state to autonomous state should be under 2 seconds.

Example scenario

The staff has to have a manual control over the smartcar, so that they can deliver the goods to the specified customer address. The staff member feels tired, and therefore is going to switch the car to autonomous state, so that the car can avoid encountered obstacles, and the goods can be delivered safely. When the car detects an obstacle(i.e wall) in front of it, it starts turning and driving to the direction where there is no wall in order to avoid it.
