My grandad didnt even have to take a driving test, as he drove in the war and survived, so he was deemed a good enough driver to carry on doing so! A little scary to be honest! He used to be a good driver though saying that, but over the last 2 years he has pretty much lost the ability to walk, yet he carried on driving. He bumped it soooooooo many times in that time. He is selling his car now for good though, years of telling him finally paid off! (though he didnt actually listen to us, it was the doctor who told him couldn't drive safely anymore due to not being able to see well enough or walk!)
