In this guide you will come to know how to change the Vehicle Access in GTA 5 Online.
The first thing you have to do is open the interaction menu by holding down the touchpad on the PlayStation. If you are using Xbox, you have to press the select button from the controller. Then navigate to the vehicle options in the interaction menu, as shown in the image below.
After that, scroll down and navigate to the Vehicle access option; if you want no one to use your car, you have to select the no-one option, and if you select the Crew Friends, then only crew members can use your car. If you select the passenger option, then only passengers can sit in your car, but they cannot drive, if you select friends, then only your friends can get in your car, and if you select everyone option, then anyone can use your car.
After selecting the vehicle access option, you will need to close the interaction menu and continue to play.
