We’ve been staying the week at this beautiful Airbnb flat, tucked under the hosts' house.…

…It includes a huge balcony that overlooks the trees and is visited each day by a wide variety of birds.

We asked the hosts, when booking, about plugging in an EV. Although they have not had that request before, they were very happy to try to assist, offering for us to drive down their driveway to plug in. Unfortunately, the top of the driveway has a tall peak, which is apparently worse than it looks, because the Tesla made an awful scraping sound when we tried to cross it. We reversed, and of course it made the same sound. So, we aborted the attempt and instead just parked across the road.

Under the car, I could see plenty of scrape marks (from this and other lesser scrapes) but I couldn’t spot anything loose.

It’s sad and ironic that we managed to travel nearly top to bottom of Australia, along some really dodgy roads, but met our undoing in a semi suburban driveway. But, it seems no actual damage done.

We noticed when we had the driver’s windows open, we could hear the car make some rattling sound from the right hand outside of the vehicle, when we drove over bumps. We thought it was related to the scrape.

Update:

A few weeks later, we asked Tesla to have a look at it. After a couple of visits, the noise turned out to be unrelated to the scrape. It was just some rattling in the plastic hubcaps, which they fixed.
