There were guys on this site that talked about these UCT problems. Many times they presented detailed facts explaining the issue. These were people who knew what they were talking about, but NOBODY listened.
There is no way to add up the total losses due to this system. How many people got hurt or worse because of it ? How much more property was damaged because of it ?
Sometimes, "high priced business people" don't always have the answers. But in many cases, our civic leaders prefer to accept their sales speech rather than somebody who knows the system from top to bottom, and has the experience and knowledge it takes to tell what really needs to be changed or fixed.
As an example, If I need the headlight replaced on my car, I don't go to a "car salesman" to get it fixed. It just might end up costing me a lot more money than I first thought.
