I can't believe you guys still drive I-5. I avoid I-5 when possible, in fact I haven't been on I-5 nearly 3-5 years. I-5 is the most direct diagonal freeway, while also being the most famous. Even if people don't know a thing about freeways, they ALWAYS know what I-5 is. Every time when I pass by on a crossing freeway, I always see back up.
Also, it's ORANGE COUNTY. No $hit sherlock of course their segment of I-5 is going to be the best in So Cal and quite possibly the entire west coast. OC is not hesitant when upgrading freeways. They are already upgrading my beloved CA 91 with a new lane from I-5 to CA 71. Not to mention, the OC has it's own Caltrans district(District 12), which means management and funds can be focus on their freeways and their freeways alone. On top of that, they are a very small county so they can focus more funds on the freeways they have, unlike District 7 that not only has to cover the already big LA County, but Ventura as well.
