- Blockchain Technology: Blockchain technology is being used to create secure and tamper-proof vehicle identification systems.
9.3. Legislative Changes
Recent legislative developments in the U.S. suggest that new vehicles might soon be required to have kill switches installed—devices that allow authorities to disable vehicles remotely. This measure, embedded in the latest infrastructure bill, has been noted by former U.S. Representative Bob Barr.
The primary intent behind these kill switches is to enhance safety, aiming to prevent incidents such as high-speed chases. However, the implications for privacy and autonomy are significant. These devices grant law enforcement the power to control vehicles and enable the continuous monitoring of drivers’ behaviours to detect signs of impairment.
Critics argue that this system, which includes a backdoor potentially accessible without a warrant, is vulnerable to hacking and constitutes a severe violation of privacy. Government agencies’ broad discretion in implementing this technology, coupled with vague definitions, further exacerbates these concerns.
This controversial provision was passed with little public debate or scrutiny, often bundled in larger bills. It highlights the need for public engagement and advocacy, urging citizens and car enthusiasts to communicate with legislators about the profound implications such technology could have on personal freedoms.
As technology continues intertwining with legislative measures, so understanding its implications’ full scope is crucial. Vehicle owners and potential buyers should stay informed about these developments, which significantly impact both the functionality of their vehicles and their broader rights and privacy.
