Learner Driver's Licence, 12 July, 2005.

After letting it lapse, a long time before.
As strange as it now seems, in the old days driving without a licence wasn't much of a deal. It was a $20 fine and there wasn't all that much chance of being caught in any case.
I drove for 20 years without a licence and never once got hassled. 
Now, with all the new surveillance technologies, combined with excessive policing, and with  motorists make the easiest and most lucrative targets, not having a licence is madness and the chances of being pulled over very high indeed.
