Two things. 1. This guy didn't just talk about traffic engineering, he specifically claimed to have special expertise
as an engineer to comment on the issue, blatantly disregarding what should have been his own professional ethics. 2. Unlike some states, it's against the law in Oregon to enter an intersection when the light is yellow, a fact not noted in the article and apparently missed by this guy's analysis.
Also, any actual licensed engineers want to comment on the ethics of using one's professional status to press a personal grudge?
