What does telemetry refer to in the context of racing?

Telemetry, in the context of racing, refers specifically to the technology used to collect data from the car’s performance in real-time. This involves the transmission of data from various sensors equipped on the car to a remote location, allowing engineers and teams to monitor critical performance metrics such as speed, tire temperatures, fuel levels, and engine performance as the car is on the track. This immediate access to data helps teams make informed decisions about strategy, car setup, and adjustments during practice and races.

The other options pertain to different aspects of racing. While improving driver communication is essential, it does not align with telemetry's focus on data collection. Managing race regulations is crucial for maintaining fairness and adherence to guidelines but is not directly related to the technology used for performance data. Tire pressure adjustments are important for car handling but are a tactical aspect rather than a technological system like telemetry. Thus, the focus on real-time data collection accurately encapsulates the purpose and application of telemetry in racing.
