Mom won't give up her driving. Granted it is about .9 miles to the local VFW, no main roads, where she goes each day but she is so off balance and can barely walk, uses a cane when she remembers and should really be using a walker. She is getting so she can't remember how to pay her bills either She is refusing to let me help her in any way--POA, etc.
Talk with her doctor and have him order her testing or send notice to DMV that she shouldn't be driving. They can call her in for testing.
See an attorney to obtain consult on Guardianship, what evidence you need, costs, etc.
I'm not sure what you mean by POA. Do you have Durable POA? If so, I'd consult with attorney to see about your authority to sell the vehicle, if she now incompetent and not able to handle her own affairs. I'd make sure I was on sound legal footing.
Another idea is to offer to transport her either by family, friends or hired transport. That way, she would not have to drive for her groceries. If this is dementia, she won't likely just give it up, though, my LO did. She forgot how to get out of the car one day.....it scared her and she hung up the keys and refused to drive. THANK goodness.
Would online bill payment work for her? She could still get the paper statements and bank statements to confirm payment.
Best thing would be to disable the car and have it tiwed to a repair shop never to return.
Your two examples are good but around here we have had more people injured in their homes when a vehicle crashed thru the wall.
We have had many people injured or killed crossing the street on on the sidewalk. So far I don't remember of any scooters being hit and I see many of them out and about.
Some use the road because the sidewalks are not compatible with wheel chairs or scooters.
It was just a suggestion and would depend on the local traffic.
