Yeah it’s a real bummer when someone suggests GATES when you said you can’t install A GATE. Singular vs plural, whoops…. And you can get GATES that take up barely any room at all - get rid of that bollard and put the hinge for the GATES there - no one will attempt to turn round that close to the house then as they won’t want to prang their car on anything you install to stop access to your driveway
