There is nothing in the CVC that requires a rider to put their foot down.
That said....
PUT YOUR FUCKING FOOT DOWN. Take the time to do more than casually glance for cross traffic while you're focusing on your balance. Yes, many of us can pause for several seconds while stopped without putting a foot down - bully that you're one of us. That doesn't make it safe, doesn't make it prudent, and your passenger is worth more than a cursatory glance down a side street for her safety.
And your "I know better what I'm doing than anyone else on the hill" attitude is going to get you real far on the street. Good luck with that, and good luck with giving attitude to LEOs.
