AIBU to be irritated by my mum's constant comments about my car?

My mums ‘helpful suggestion’ to everything I experience or decision I make in life has been that I could get rid of my car and that would save me money. She’s obsessed. New job? You could work from home and get rid of your car. New house? You could buy close to work and get rid of your car. Need to save money to pay for a holiday/house repairs? Get rid of your car. It’s always my car, not DHs she thinks we should get rid of.

For context DH and I have a car each to get to work, and 2 children who need to be picked up from school and taken to clubs and parties from time to time. Both cars are about 10 years old and owned outright and cost very little in the way of tax and insurance, so even if we did get rid of one it wouldn’t save much money, but would be inconvenient because we’d have to work out a schedule of who needs the car when and potentially be dropped off early or picked up late for things.

My mum fixates on random stuff. She's decided (having never seen my home - live in different countries) that I need to fix up the front of my flat. Every phone call and visit she asks have I called a landscaper, why not, does it look awful etc. Tried to give me money last time to fix up blah blah. I don't know where the anxiety is coming from but it's bonkers. I eventually said this isn't happening and it's not up for discussion. Now she's moved onto obsessing about whether we're cutting the back lawn more than once a week. Arghhhhhhhh. She was always obsessive and controlling but I wonder whether it's cognitive decline because it's becoming properly barmy.

Not helpful, sorry OP, but solidarity!

Thank you! Yes I forgot she’s also fixated by helping me do the gardening, I’ve no interest in gardening whatsoever, never have done, when she comes to visit she plants stuff in pots which I am then invited to admire, which then invariably dies because I haven’t the inclination to water plants I didn’t want in the garden I’m not interested in.
