Driving levels mainly apply to the driver and make a difference for him being in charge of the vehicle
or not. However, all other persons on board of a vehicle no matter if on the front passenger seat or on
rear seats are passengers no matter which driving level applies.
6.1.1 Matching of generic multimedia use cases with driving levels

The following table matches generic use cases and services with the driving levels. All activities that
are mentioned in the table should be considered for a driving vehicle. When the vehicle parks or
stands still, all services are available for the driver as well as for the passengers. Excluded in this case
is a standing vehicle at traffic lights or other traffic signs as in this case the vehicle and the driver are
still considered as active traffic participants similar to a driving car.
Within the driving levels a distinction on what drivers (D) and passengers (P) are allowed to do in the
framework of these use cases and services is taken into consideration.

= Allowed

( ) = Partly allowed (in autonomous driving mode)
Figure 4 – Matching of generic multimedia use cases with SAE driving levels

The above table follows the guidelines of current legal framework in place in some jurisdiction.
(e.g., US and EU. Note: Some other jurisdictions may use similar or different classifications than
those in [SAE J3016]). However, from an ergonomic point of view phoning or getting read content
while driving through text-to-speech can lead to a cognitive overload for the driver and can lead to
critical driving situations. Therefore, for driving levels 0 to 3, it is suggested to integrate driver
monitoring into the vehicle in order to measure the cognitive load of the driver and to adapt access
and content to driving situations and distraction level.
In addition, driver monitoring in driving level 3 facilitates tracking if the driver has taken back control
when requested or if alternative actions need to be taken in order to bring the vehicle to a safe stop.

7 Connectivity

7.1 Distinction between brought-in, built-in and hybrid connectivity

In-vehicle connectivity can be distinguished in three connectivity cases, that is, brought-in, built-in
and hybrid connectivity.

7.1.1 Brought-in connectivity
The multi-media system of the vehicle is neither connected to the internet nor to other connected
services and applications (maybe with the exception of radio FM). Due to legal requirements in
