I have no friends or family here and am too socially crippled to make friends I would ever trust. I need a harmless procedure completed and doctors refuse to do it unless I have someone else with me who is willing to drive me home afterwards. Uber/Lyft/Taxi is not allowed either.
I've been in the same boat for most of my life. I've been lucky enough to make a few friends in the past few years but that's not to say that I trust them with my life.
Use an online service to hire an assistant who can drive.
