Just had Ice Cream Sandwich installed on my Droid Bionic (about time) and smart actions came along with it. My question is: What triggers the driving action? That is, how does the app detect that you are driving? If it is based on speed, then I assume GPS needs to be on and at what speed do you have to be going to activate? If that is the case, what prevents the action to turn off at a stop light? The reason for my question is, I set this up and it didn't seem to activate... I love smart action otherwise - thank you so much.
