DS is nearly 18 and has got a driving test booked next month. He’s had loads of lessons (think I’ve paid for 70 hours of instruction at least!) and his instructor says he is test ready and should pass. I bought him a little car a few weeks ago and I’ve been taking him out in it to practice. DS wants to drive to visit his grandma (my mum) an hour away, accompanied by me obviously as he is still a learner. The route involves fast dual carriageways and then winding country roads. I’ve said my nerves aren’t up to sitting beside him at 70mph on the A3 but AIBU? He thinks I am because he has been on similar roads with his instructor and had no incidents - and he says how can he get experience if I won’t let him.
