Useless, by the time it gets released in the US, all you can use it for is to lock and unlock.
Look at the BMW remote app, you can't even do door lock/unlock or fan.
It only can honk and turn on the light.
I think it is more usefull if they just enchance the app to let us use our "smart" phone to lock and unlock the car, plus other features.
Not that hard to do.
