"DRM in Cars Will Drive Consumers Crazy
Forget extra cupholders or power windows: the new Renault Zoe comes with a "feature" that absolutely nobody wants.
Instead of selling consumers a complete car that they can use, repair, and upgrade as they see fit, Renault has opted to lock purchasers into a rental contract with a battery manufacturer and enforce that contract with digital rights management (DRM) restrictions that can remotely prevent the battery from charging at all.
Unfortunately, the intentional restrictions created by DRM can also create security vulnerabilities that can be exploited by other bad actors.
The most prominent example may be the "rootkit" that Sony included on music CDs and which led in some cases to further malware infection.
The stakes may be even higher when it comes to cars. Security researchers uncovering security problems in cars already face restrictions on publishing; that stands to get worse as DRM enters the picture.*"
