Tried to rent a car in Panama, but the counter guy wanted me to sign a charge ticket without an amount filled in. NOT HAPPENING! So I just used Uber.
Norway (never rented a car, but lived there and drove a van my employer provided - my regular wheels - as well as cars owned by friends; also drove a panel truck with four-on-the-floor to take my road test for my commercial license)
Funny thing - I’ve visited 17 other European countries but not ever driven, much less rented a car, in any of them.
