Why did the car keep going after it hit the semi? It went through two fences and hit a power pole. Shouldn’t its collision avoidance systems have at least registered it hitting the fences if not going under the semi?

We’ll never know all the details, and I think the truck driver was definitely at fault and I still think the Model S is an amazing car (I’d have one of I was rich). This just confuses me.
