The Mazda3 and Volvo V60 you specify do not provide full high speed automatic braking and will not prevent a collision at 25mph according to the IIHS.  The Toyota TSS-P system, standard on Corolla, Prius and other models prevents front collisions even at high speeds and also detects pedestrians.  The article may be highlighting vehicles with incentives but omits other cars with better safety features at lower prices.  Buyers should look closely at the IIHS web site in order to find what trims include the best safety features and the best headlights.
