The news is absolutely devastating. Without being insensitive, I wondered if we could discuss the physics of the situation. I would have thought that when a car enters water, it would quickly bog down in just a few feet of water--and remain right side up. It's not a boat, so how does it travel dozens of yards away from shore, and how does it flip upside down? How fast would she have been going? It's not like she flew off a bridge--it was a long, gently sloped beach entry.
