I must admit, I had assumed the police already had access to the DVLA data including photographs, so the new provisions makes no practical difference to me. I too believe we should all carry some form of ID which is biometrically linked to us, so when a medical issue arises the hospitals anywhere in country can access our records to assist with diagnostics and treatment.
And before the civil liberties groups get on their high horses, we already have so many occasions now when we have to verify who we are to access services, it's hardly going to infringe any more of our rights.
