Guter Artikel hier über die Risiken eines direkten Datenzugriffes in Fahrzeugen und aus meiner Sicht deutliche Gründe dafür, diese Daten nicht unkontrolliert Dritten zur Verfügung zu stellen.

Direct third-party access to vehicle functions can facilitate hacker attacks, since every new external data interface increases the number of potential targets and entry points.
Even uncontrolled third-party access to vehicle functions or data that are not directly security-relevant can lead to risks through networking. This could enable car theft or the remote unlocking of a door, for example, as well as creating opportunities for fraud or the theft of your personal data.
Endangering safety-critical functions
Similarly, safety-critical functions such as braking can be affected negatively by the use of in-vehicle resources and computing capacity for unapproved third-party applications. Your car doesn’t have nearly as much processing power as a computer. It couldn’t possibly handle the volume of data requested, or the frequency with which it could be requested, if dozens of service providers would be granted direct and uncontrolled access.
Additional safety risks in terms of driver distraction can arise if external third parties have uncontrolled access to your vehicle’s on-board systems, user interfaces and function displays. This could happen, for example, through apps or additional control units that would draw your attention away from the road.
Giving direct and uncontrolled access to the data inside your car, van, truck or bus might also lead to unintended consequences from the installation of additional software. This includes the potential for serious malfunction or even a crash of the system. Something that may not be too worrying in, say, your smartphone, but can represent a serious risk in a moving vehicle.
