There are some issues with the deployment of level 3 vehicles.
Just last year Mercedes Benz as the first company S class at level 3 released. Other vehicles at this level will soon follow. TheLaw is in Germany already been adopted in 2017 and for a few months the vehicles should even be included 130 kilometers per hour run.
With level 3 you can take your hands off the steering wheel under certain conditions and devote yourself to other things. However, you have to be back on track within ten seconds and take control of the vehicle. Traffic researcher Nadja Schömig from the Würzburg Institute for Traffic Sciences sees the level of automation as a problem Human-Machine-Interface (HMI). Above all, she asks whether ten seconds transfer time enough?
In experiments with games and memory tasks, the researcher checks the time required. The bottom line is, ten seconds is okay if certain ground rules are followed. Sleeping like this is not possible. Holding objects such as a cell phone or something to eat also becomes difficult. How to quickly drop a dripping treat to take control of the vehicle.
The car already has to monitor the drivers and check whether their eyes are focused on the traffic. The software must be trained to anticipate driving behavior. Small exercises could also be planned, but then you are no longer undisturbed. At Mercedes-Benz, the operating instructions tell you what is allowed. Sleeping, moving from the seat or continuously looking backwards are not allowed.
For data protection reasons, this analysis must be carried out onboard and must not be transmitted. That costs too computing capacity in the car.
