General Motors is working on an app for the iPhone and rival Google phone for some of its cars sold in the United States. The phone application will allow drivers to activate all of the traditional key fob features, including unlocking the doors and opening the boot. There will also be a remote start function that could prove handy for warming up the car on those colder mornings (or cooling it down during summer), and if you forget where you parked you can set off your car’s horn and lights at the touch of a button so it can alert you to its location.
