Hi Vicky,
My two both drive now and yes, it is and probably always will be a worry. I am actually more anxious about my son on the road than my daughter. She has a better perception of her place in space than he does... if that makes sense to anyone else but me. They both did just fine with both the tests here. Similar system by the sound of it. They did a written test and then had to have so many hours under instruction and then they did the driving test on the road. I think a lot of it is just experience although getting experience on the road these days compared with when I got my driving permit is totally different. I've always been a defensive driver. i.e. aware of everything that's around me at all times. I think that's something I'll pay them to do as soon as possible... a defensive driving course.
