I bet what happened was ... something the car did in full self driving mode scared the driver and they attempted to slam on the brake, but hit the gas instead resulting in a crash where they are accelerating into the home.
That sounds quite plausible!
Also possible, I can file a lawsuit that Tesla’s car did something unsafe and almost kilt me! let’s put it in auto drive and say it just sped up on ots own with me in it! payday!
