It will cut out some paperwork, not only do we have to give the 'verbal NIP' and document that but there is a force poliey that means a written NIP has to be sent out ot the driver, recorded post. And if a job, where an NIP was not given gets past the Evidence Review Officer, Criminal Justice Unit, the Crown Prosecutor, the file builder in the CJU, and is only noticed on the day of the trial at Crown Court by the Prosecution, then a great deal to money and time has been wasted.
No NIP, save time and money.
No one has ever given a satisfactory answer as to why it's needed anyway.
