Then there is the other angle to look at, if everything is already installed on the car but you have to pay extra to enable the software to use it. Then there will be some bright spark out there somewhere who could produce a hack for the software so you could upgrade and use the extra features for free. It is completely possible to have cloud based software which relies on the cloud to be hacked and then redirect the software feature license so VW are none the wiser. VW may have to ensure their security encryption for the software is water tight if they expect everyone to pay to enable the features. Also if there is more features on the car relying on cloud based software, it may become easier for criminals to mess with and/or steal your car.
