Dr. Wes Marshall, a professor of civil engineering at the University of Colorado Denver, in his book _Killed By A Traffic Engineer: Shattering the Delusion that Science Underlies our Transportation System_, digs into the standards that have dictated traffic design for decades to find out exactly how much science they’re based on.

> Are traffic engineering decisions based on evidence-based research? Not as much as you might think.

The automotive engineers who are trying to develop driverless cars and automated cars are trying to correct the unsolvable problems of poor road design and traffic congestion. Have they included in their design the automatic shutoff of the systems when the road system is too complex or when the supervising driver is not paying attention?
