done but a bit annoying! "Do you check your phone less often?" smacks of "have you stopped beating your wife?"
Standards of others? vary hugely
A few years ago, I was very concerned that my driving was not as it should be, so I did the Institute of Advanced Motorists test which was hugely satisfying - to me. When an advanced police driving instructor of many years experience told me that I was a good driver and that he had enjoyed taking me out for my test, I felt great. I can still make mistakes but have been trying for years to pay more attention, be less distracted etc etc and having the DGC has not affected that. The programme is very worthwhile, particularly if you feel that you may have picked up bad habits over time, or are losing confidence.
