> result is mass deaths and injury

Do you have some hard evidence that shows that most traffic accidents are caused by people not complying with speed limits vs. people being inattentive, people under the influence of drugs or alcohol, people making invalid turns, people slamming on their brakes but the driver behind them is unable to react in time, etc.?

The notion of "speed kills" is not always correct. If everyone on the highway is driving above the speed limit, then driving at the speed limit and slower than the flow of traffic would actually become a cause of traffic and increase the risk of a collision.
