The Sunday Times has reported that the government are drawing up plans to double the fines for using a mobile phone whilst driving. There also are hints of updated the legislation to take into account smartphone technology.
This may be in anticipation of the Crown Prosecution Service (CPS) that will have to run the gauntlet when prosecuting the first smart watch offender
(the Apple watch being one such device).
Worth watching out for (on your device, but not at the wheel).
