Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“We had begun to cross an intersection and, while our speed was from a dead stop, the other driver blew through a red light and hit us at what was probably the speed limit of 40mph. Her car struck us in the right front passenger side and again on the rear passenger side. We, myself who was driving, and my wife, who was the passenger on the side hit, were both thrown hard to the right at impact, causing injuries to us both, most notably, my wife. She hit her head very hard on either the passenger door frame or the passenger window. No airbags deployed. No side airbags, no front airbags. …”
