My Mum would say I was bossy and isn't talking to me at all right now because the issue of her driving came up! Sadly, she is confused, ill and is losing her ability to rationalise. Despite being frail, unable to do cope without considerable assistance, she still believes she is omnipotent. Believe me, I'd love to be able to shrug my shoulders and let her get on with it but if she doesn't kill herself, she'll kill other people. The rest of the family and her friends, including her partner, are aghast that she is still driving but I seem to be the only one who will tackle the thorny issue.
