Just emailed the link to my parents who are permanent residents in Spain. My father was aware of these measures coming into force. Once they have been voted upon he says that they will become law with immediate effect. He also thinks that because of a UK opt out any points that are incurred there are not transferable to a UK licence but as I say this is what he thinks. Also 1km over the speed limit could only be head line grabbing by the Daily Mail, surely?
When he told me about these laws being proposed a couple of weeks ago he also said that not only does it apply to radar detectors but also to Sat Navs that show camera positions etc. and it will be an offence to act on the information provided by them in regards camera sites etc.
His final comment in his email was "Just have to obey the rules, my days of enjoying fast driving on largely empty Spanish motorways is now at an end, had a good time whilst it lasted, it's going to be so boring." This is a little sad to hear from him as he still likes to go "Harry Flatters" in his 335d coupe. P.S He also said that he has now removed his radar detector.
