[CA] Uber passenger

I was just getting home from a work trip and took an Uber. The Uber driver was on the freeway when we came up on dead stopped traffic. Right before coming to a complete stop, the driver decide to swerve into the fast lane to avoid waiting in traffic. We were immediately hit from behind by a car going about 65-70 mph. The Uber driver is 100% at fault.

I opted to get taken to the hospital by EMT, as my neck and lower back began to experience pain. CT scans came back negative for spine damage.

I submitted an accident claim with Uber and got the accident report number from CHP. What are my next steps?

I'm currently in a lot of pain, and I'm shaken up emotionally and can't stop thinking about the fact that I was almost taken away from my wife and kids because an Uber driver wanted to make the trip as short as possible instead of focusing on driving safely.
