Allow virtual key sharing and removing (as been implemented, but this website dosen't allow me to mark it as so)

I'd like to be able to share a key with familly. My dad has is tesla with is account and I have my tesla with my account. I'd like to be able to share a key with is user name/email and revoke it later. For now I need to login in my account and then he is logged out of his account ...

Also, i't would be nice to give key to friends that expire. For example transfer a virtuual key to the detailing shop, or to a friend that is borowing the car for a weekend...

As it's possible for smart key in houses

looks like it's possible through the website now : https://www.teslarati.com/tesla-car-access-robotaxi-remote/
