Safety is quite strong for the 2010 Matrix. Stability and traction control are newly standard for 2010, and dual front, side, and curtain airbags, along with active headrests and anti-lock brakes, remain on all models.
Crash-test ratings are good but not class-leading; in federal testing, the Matrix earns four- and five-star ratings for side impact but five stars for frontal impact. Results are also mixed from the insurance-funded IIHS; in that group's testing, it gets just "acceptable" ratings in seat-based rear-impact tests but "good" results in frontal offset and side impact.
If you're shopping the 2010 Toyota Corolla Matrix against other small cars, you'll find a number of smaller features that aren't included in all the vehicles. For instance, Cars.com notes that "all five seats have head restraints, and active head restraints are standard up front."
Outward visibility might be somewhat frustrating in the 2010 Matrix, depending on the height of the driver. ConsumerGuide says that "visibility is poor to the rear corners."
