Virginia State Police (VSP) launched a project to test the resilience to cyber attacks of police cars (models 2012 Chevrolet Impalas and 2013 Ford Tauruses) Researchers demonstrated they could make shift gears from park to drive, cause a spike in engine RPMs, cause the engine to accelerate without applying a foot to the pedal, and turn off the engine completely. The hacks of the VSP vehicles require initial physical tampering of the vehicle as well, the researchers used rogue devices that were installed in the police vehicles.”]
