16: Voice-Activated Car OS
It started with Ford and the SYNC system they used on the original Ford Fusion. Now almost every car has some sort of voice-activated system. There are a few uses to the voice-activated system. The first is of course to talk on the phone and get updates through your car when you are on the road (via Forbes).
A voice-activated system is also great for protecting the driver in case of an accident. It can be activated so that the proper authorities can be called. No matter what the main use for these systems is, they have dramatically changed the automotive industry.
