Technology of cars and in cars has evolved rapidly with the move towards the smart cars. Smart cars are characterized by many additional sensors, almost permanent connectivity to the producer’s software platform, the internet, autonomous driving capability or, potentially, remote control. We might still curse some nostalgic feelings of being in driving seat, but the supervision of our capability to drive and monitoring of behavior has reached impressive levels of perfection beyond the fasten your seatbelt sign and alarm. The software that is driving our cars has become the challenge of the coming years and with this the concern for data privacy and cyber security. Smart cars have multiple cameras to guide driving and parking effectively. These cameras are also a perfect spy even around or in your home. From our smartphones we all know the scanning of connectable Bluetooth devices or wlan nearby. Smart cars are powerful assistants in data collection sometimes even beyond your control, for example who these data are sent to. June Yoon (2024-10-2 Financial Times) has developed this rationale even further to stir up additional fears: “A hacked self-driving car might even be turned into a weapon”. The weaponization of beepers, talky-walkies is certainly not the last step in this process of potential dangers of technology. Smart cars come with additional risks, not only additional comfort. Better choose your rollercoaster wisely.
