Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 1.0% of tests record it — this model is 3.0× that share |

| The model's own record | 538,036 tests · every year of the Prius → |
A share of tests is not a probability for your car: it counts every Toyota Prius tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
