It seems STS is really keen to test the limits of the system. Please do report back once you've jumped a few red lights (which you seem to proactively prepare for in CA) when next in China in your FIL's car. I'm genuinely impressed by your willingness to spend so much time beating the system...you've done a brilliant job in the US. So I think that's no longer a challenge...and you're hankering for something to really test your mettle.
