Latest info I found, today, 8:47 AM PST 01/22/2022:
“Police told reporters a red Prius was making a U-turn as it continued through a ‘red arrow’ signal to turn left when the collision occurred, causing the SUV to roll on top of the Prius and hit two other vehicles.”
I read it. Looks like a hell of an impact for someone making a U-turn, which are mostly performed at low speeds. One of those vehicles were moving fast to cause the Toyota to go underneath the SUV, nearly causing the SUV to roll completely over. That’s a lot of force. I’m not really buying the U-turn narrative. We’ll have to wait and see what the investigators say.
