Personally, I think the app should be fully disabled while moving fast passenger or not.
Would you kindly submit a list of which apps should be disabled and which apps should be allowed to function while moving at a certain speed? Do you believe that behavior should be forced by the app or the OS? Who makes these decisions? Should it vary by jurisdiction? What about in a taxi cab, on a train or a bus? Should we have a different standard or even law for all these scenarios? Or we could, you know, have a trial and determine if the driver was criminally negligent regardless of what activity he/she was engaged in?
