We are truly sorry to hear it.
For the real LA experience, I recommend driving the freeway during rush hour, which for your convenience, runs from 4 AM to midnight.
A slight exaggeration....
There are times that the freeways are just fine. Sure, the to-and-from-work rush hour times are a little extended compared to most other cities, but to imply that the freeways are rammed from 4am to midnight is just not accurate.
For example, here is a screenshot from around 11am (which falls between your 4am to midnight period) from Google Maps. Looks pretty clear to me. I bet I could get to Culver City from Westwood in 5 minutes or to downtown in 15-20 minutes right now.
