Are you legally required to carry a means of communication? If not, how can this possibly be enforced? It sounds like an end run to get to negligence charges.
For example, how fast can I drive to get to a telephone if I don't carry one or otherwise cannot use it?
There's a discussion of the difference between American and German tort law here: https://supreme.findlaw.com/legal-commentary/how-germany-vie...
The difference is that German law is more systematic and includes a general duty to rescue, but this doesn't result in excessive negligence charges, as awards are much smaller.
