I took in my Mazda3 to have the screen replaced. There was an issue with the sensors that mistakenly thought someone was touching the screen. At low speeds, when the toch screen re-activates, it would start navigating on its own; from changing music stations to calling people and changing GPS waypoints. Drivers trying to stop this will be more distracted than they otherwise would be. This happens at stop signs, red lights and slow-moving traffic.
