My mother has dementia and is unsafe on the roads. After much soul searching I reported her to DVLA, who sent her a form. Because her car is now neither insured nor taxed, we have taken her keys, so she can't 'forget' and get in and drive. She has discovered I have her keys and insists I send them to her. She is getting very verbally aggressive about this; threatening the police (theft) and cutting me out of her will. She is furious as it is, in her eyes, the last of her independence. This is terribly upsetting! I don't know what to do. I have told her that, if she hears back from the DVLA that she can drive again (unlikely!) then I will return her keys. Any suggestions as to how to placate her? Any thoughts on my rights here? I do have LPA.
