The key is the presence of FSDT... which as Six jours mentioned, is a fairly constant component in Southern California.
You specifically mentioned weekends... where of course the presence of FSDT can vary widely as a function of time of day.
Otherwise, when enough FSDT is present to slow that traffic to below the posted speed limit, then no doubt no gaps exist... and you will be right biased at that time. That "slowed traffic situation" is commonly called "rush hour" which anyone in SoCal can tell you is an condition monitored nearly hourly on broadcast news.
