Don't know about their credibility but I wouldn't begrudge the "chairman" $13/hr.
"Numerous traffic studies have shown that camera systems reduce right angle crashes (T-bone crashes) by as much as 70 percent. Typically, rear end crashes increase a few percent, but nowhere as much as the more deadly right angle crashes are decreased."
I also don't know about "numerous traffic studies" or how "stellar" the state of VA is but their studies found vastly different results than your studies.
