You can drive here for three months on your stateside license, but that's the least of your worries.
An attorney will be happy to take your money.
Cars are expensive here.
It can be difficult to find one without issues.
You really don't want to have an accident here, of which the probability is high if you are driving.
I'm trying to balance wants/needs/realistic possibilities.
If I stay here only one month I'll continue as I am, using taxis and Ubers as needed.
If I stay here 6 months it changes the equation but it still sounds like I'd be better off using Ubers mostly.
A year or more; I'd definitely look much harder at self driving.
I'm kind of unsettled. Santiago is very nice, at least the neighborhood I'm in, and people are polite but I don't know anyone here. The biggest issue for me is that I don't really know how to be retired, especially when so much of the world is closed off to the plans I had made previously. I want to stay in one place for a couple of years at least but I don't think RD is that place.
Sorry for venting a little, and thanks for the helpful input
