She learned to drive a car when you didn't need a licence - or at least there was no driving test.
My wifes grandfather got his driving license at 15 during WW1. The local doctor needed a driver and all the able-bodied men were away or doing Important Stuff
His test consisted of the local constable watching him drive round the town square.
 This being Cornwall, Important Stuff == mining, fishing or farming. Because he was a nice middle-class lad (his father owned a shop), he didn't qualify for any of those.
