Re: So one needs an app to use the car?
No, you don't need an app to use the car. Without the app, you have to live with the dreaded inconvenience of having to do things such as telling your navigator where you want to go instead of it getting the information from the calendar on your phone, and you have to carry your fob with you to get into the car. If you can't live with that, you probably can't live with any car.
