How Do I Restrict My Ex/his Fiancé From Driving The Car I Provide Our Daughter?

I will be providing our 17 year old to take my car to school once she gets her license. (On her permit now) She is a great child - honor student - does not drink or party at all. She is probably a better driver than me since she literally follows the driving manual to a T!

The issue I have is my ex just announced he is moving clear across town so instead of 5 miles a day roundtrip our new driver will be going 25 miles a day when she is with her dad. It's a busy part of the city. And he does not seem to have a reliable vehicle at this point in time.

He is driving his mom's old SUV (2010ish) which he bought from her with the insurance proceeds from a different car he totaled in a drunk driving accident 2 years ago. And the woman he is moving in with is on probation for her 3rd DUI and is not supposed to be driving but shares a car with her mom who is elderly and also will live there. Grandma is the only one in the home who seems to work full time. So our child will likely have the newest and most reliable vehicle in the home. She is on my insurance and the car is solely in my name. (Its a 2020 with 75K miles so a nice car for a child to drive to school)

I have been clear with her that it's a privilege to have a car and she is not to allow anyone to drive it under any circumstances without my permission at that time - including friends and family. I also know her dad is a bully and general lousy decision maker from things he as done in the past few years regarding out kids.

Example of what I deal with : He drove this daughter to my home while I was out of town to get something and she asked him to wait in the car. He decided she was taking too long and followed her in and was seen on my cameras mocking my home, going through my mail, etc. She was recorded in tears pleading with him not to go into my bedroom and he did and then used my bathroom.

I plan to send him an email clarifying this but are there other avenues I can take?

I want to allow her to have her freedom, but her dad and his GF are reckless.
