In a few weeks, I have business meetings in Monterey until late Monday and then an 8 AM flight Tuesday. For various reasons, I am going to stay in Monterey and then drive up to SFO early Tuesday. And, yes, I know that I should just go up late at night, but it doesn't work for a number of reasons.

What kind of traffic would I see on the 280 North around 6 AM? How much extra time should I budget over the 2 hour traffic-free drive?

Alternatively, would it be better to take PCH all the way to Half Moon Bay and cut over?
