Which is not a common source of customer feedback for drivers?

Personal conversations with friends are not a common source of customer feedback for drivers. While drivers might discuss their experiences or rides with friends, these informal conversations do not typically provide structured or actionable feedback. Instead, drivers rely on more formal and direct channels that reflect customer experiences related to their services.

Rideshare app rankings and feedback forms after rides are specifically designed for collecting customer opinions and can provide valuable insights into driver performance and customer satisfaction. Online review platforms also serve as a significant source of feedback, as they compile reviews and ratings from various users, offering a broader perspective on a driver's service quality. These sources help drivers understand their strengths and areas for improvement based on customer interactions.
