Car seat manufacturers are now required to include an additional safety strap on all car seats. The purpose of this strap is to create increased support for the base of the seat. This law came into effect in January of this past year.
Members of the safety committee believe these straps are a necessary addition and are following a precedent set by top tier companies, who opted to include the straps three years ago. However, many consumers believe the addition of the safety strap is unlikely to decrease the number of injuries reported because one major factor that contributed to the car seat bases not functioning properly was user error in strapping in the seat.

Assuming all of the following are true, which most logically completes the argument above?
