Since no one else has said it, this isn’t a design flaw of the truck. The operator didn’t let air out of their tires. Before driving on sand you really want to let your tire PSI down to like 15 to be safe. I used to pull hummers out of the beach with my old four cylinder Nissan pickup because their drivers were often overconfident they didn’t need to deflate their tires (or just completely unaware). I don’t like Tesla but this is an operator error, not a fatal flaw of the truck.
Wish they would do this for Rust. It’s the only reason why I even have a Windows partition anymore.
