Salespeople are incentivized to enroll customers without proper information, which results in customers unknowingly signing up for programs that benefit the car manufacturers financially. While car companies claim it's for safety, some customers have no idea they are being monitored, leading to increased costs for insurance without their understanding. The financial benefit from selling customer data is meager for these companies but significantly impacts customers. This scenario reflects a shift towards a surveillance capitalism model, where companies leverage customer data without full transparency.
