Cell Phone

One I have thought about for sometime is inspired by a friend who while otherwise very smart and wise cannot stay off her phone while driving. She is so busy that she is always on the road and always on the phone.

I want an app that detects when a person is in a car or vehicle and intercepts phone calls by telling the caller that the person is in transit and asks that they call back. There could be some sort of option for if the call is an emergency so the driver could pull over if need be.

I just want my friends to be safe.
