It’s definitely a serious concern especially as visibility of small children from high set SUVs is atrocious. So easy to run over even a 5yo. Maybe frame it as a matter of costs too, if she’s not receptive to comments on her driving skill (and I say this as someone who sucks at parking) If not the cost to fix the car, because maybe she thinks it’s nbd, then the reduced value of the car when it’s time to sell.
