About four years ago, my then-86-year-old father (since diagnosed with Parkinson's) got into a car accident with my stepmom in the passenger seat. No major property or personal damage, but Massachusetts took his license away; the car (even though it didn't appear that bad) was eventually declared totaled by the insurance company. For the past year or so, almost every time I talk to Dad on the phone, he says this is the week he's going to start to get his license back (and he's got his eye on a Toyota FJ Cruiser). I believe he had gone to the DMV once and they told him he needed a doctor's signoff. He's also going to run out of money in about a year, which renders any notion of buying (and insuring) a vehicle moot. How should I respond? Grit my teeth and let it go? Remind him of the obstacles? Something in between?
