test drive a car...without ever getting in it

Granted it is only in Norway but Volkswagon has come out with a way way cool and innovative marketing campiagn. So this is how it works. There are various ads in magazines in Norway of  a road in winter/ summer (depending on the mag you get) and then you get an app on your i phone and when you hold your phone over the road you can test drive the car. COOL. the only thing is i don't own an i phone nor do i live in norway but the video demonstrating it was interesting. very smart use of technology. the only thing that is kind of frustrating is that EVERYTHING is an app for your phone these days which kind of decreases its value / my interest level. And i just wondering how exactly it works.
