10 years is a large margin. Maybe 4 or 5 years is a better time span.
I've been driving for just under a year now (and drivern around 7k). I'd like to think I am a decent driver, I have good awareness which has come from many years of cycling and also from being on a motorbike. I understand how a car handles closeish to the limit but if I stepped over the mark I don't know how I would react which is why I want to go on a advanced dricers course.
My advice is take ur time, don't let other road users get on your nerves and mostly enjoy it. Sometimes there isn't nothing better than a long driver down your favourite roads with your music on.
