The ‘Usage’ sub-score can start to go down when there is a trip longer than an hour and doesn’t include any breaks, or if many trips are made in one day.

Driving for more than an hour without breaks can cause fatigue, reduced focus and slower reactions. Long or back-to-back trips greatly increase the risk of getting into an accident as it can lead to “road hypnosis” where your brain goes on autopilot, increasing the chance of failing to spot hazards.
