as i said before......not so painless and simple if you loose it off your person or someone steals your car....the old system of producing it at the station worked well for years and was safe,if something is not broken why fix it?
How do you know the old system worked well for years? I'm sure there would be a reduction in unnecessary admin if everyone simply carried their licence. A reduction in administration means a reduction in costs......
Clearly it makes sense to carry it while you are driving, just as it makes sense to carry a passport while you are travelling. The law is the law.
In any case you had your licence with you but preferred to keep that a secret...I'm still kinda baffled as to why you would do that....
