I don't think anyone will be concerned with the fuel trims at that moment and the resulting air pollution.
I have personally experienced many broken valve springs in cars and trucks. You are correct the ECU will put the car into limp mode but more times than not it is still drivable. I'm sure i'm not the only person to see/experience this either.

While I haven't been a resident in California for very long I believe they(EPA/CARB) would be concerned about the resulting air pollution you are emitting from the failed spring. But i'm just speculating as i'm just a tech and not part of the board.

To piggyback off of jsimon my girlfriend drove 3 years on expired tags and was pulled over a couple times and never questioned about expired reg. Risk/reward I suppose but I wouldn't advise it
