It was a Sunday when I turned 17yrs myself and, was the custom in those days, there were no lessons on a Sunday, let alone any shops open.
Well he had his first "proper" lesson in a Ford Fiesta. His instructor said it was OK for me to take a photo of him next to the car as it was free advertising for him, indeed!
I have taken him out for half an hour or so each day since his first lesson. I took him to the road his instructor had started him on the first day, a few stalls but not bad.
Day two we took full advantage of our local supermarket being closed on Christmas Day so we went there despite the rain. It was nearly empty, save a few people recycling, practicing handbrake turns in the wet and a motorcyclist with cones to practice his maneuvering.
He's getting better each day, although he doesn't see it himself, excellent!
Obviously you had to wear your Santa hat for driving on Christmas Day didn't you?
