Trouble is that Police can stop you at any time of the day for any reason and ask you your name and address and if you refuse to give them your details as you state then they will take you to the station to continue their enquiry.

It’s al very well detailing that you don’t have to give your name over etc but it just isn’t worth the hassle.

I used to get asked by the same policeman regularly on a Thursday night on the same route coming from the same place at about the same time just before midnight.
