Vehicle features "whiplash injury lessening" ("wil") seats. I argue these seats led to dramatically severe injuries. The literature published by Toyota in connection with the alleged safety of the seats implicitly states that benefits inure to those in lower-speed rear-end collisions. No study seems to indicate severity of higher-speed rear-end collisions. Specifically, whether or not wil seats actually benefit low-speed rear-end collision injuries while worsening high-speed rear-end collision injuries. I hypothesize that they worsen high-speed rear-end collision injuries, greatly. I was in a rear-end collision involving a vehicle hitting the Toyota Corolla with wil seats I was driving at or above 75 mph. I suffered 7+ slipped discs along spine, as well as a fractured vertebrae. The vehicle was in motion as it was struck from the rear, and the vehicle I was driving was moving at or about 75mph. The vehicle colliding with my vehicle was driving 75+ mph.

Bought the car new in June 2014. After a few months of driving, I have developed bad neck and back pain due to the design of the seat and head restraint. I like T O sit straight and the head restraint is forcing me to keep my head bent forward, which after a few month, has cause me to head neck and back pain.

My complaint is not with Toyota, it is with the new standards that require an extreme angle in the headrests of new vehicles. I am unable to use the headrest in my car unless I adjust the seat to recline and use a cushion behind me. The owner's manual advises against both practices, and they don't seem very safe to me. When I sit properly, the headrest forces my chin into my chest and causes neck pain and headaches. The headrest angle is not adjustable. My research shows that many others are having this problem as well. I understand that this new configuration is required by your standards to prevent whiplash injuries in accidents. Please reconsider your ruling on this issue and allow us to drive safely and comfortably with adjustable headrests. Is it better to injure all of us to prevent whiplash in the few who get hit?
