Monitor and Complete Test with Device

What happens here

As the vehicle accelerates, a performance measurement device (like the one shown in the video) actively records data. The device will automatically detect the start of acceleration and conclude the test when the target speed (e.g., 60 mph) is reached. Once the test is completed, the device will typically indicate 'Test Completed' on its screen before displaying the detailed results.

Goal: Allow the performance device to automatically record and finalize test data.
