According to the IIHS offset crash test results that just came out 11/1/13 on the Prius V, it sounds like you'll have a lot of trouble ever walking again if you crash in a Prius. Consumer Reports just dropped the Prius V from their recommended list. Here are their comments.
The driver's space was seriously compromised by intruding structure. Lower intrusion measured as much as 35 cm at the lower hinge pillar, and the upper hinge pillar and instrument panel intruded 17-22 cm. The parking brake pedal was pushed in toward the driver 20 cm, and the steering wheel was pushed in 7 cm.
Measures from the dummy indicate that injuries to the left hip and left lower leg would be likely in a crash of this severity. Head acceleration from the instrument panel hit was low.
Restraints and dummy kinematics
The dummy’s head barely contacted the frontal airbag before sliding off the left side as the steering column moved 13 cm to the right. Additionally, the seat belt allowed excessive forward excursion of the dummy’s head and torso, permitting the head to hit the instrument panel. The side curtain airbag deployed too late during the crash, dropping onto the back of the head and pushing it outboard of the inflating curtain, leaving the dummy's head vulnerable to contact with side structure and outside objects. The side torso airbag deployed.
