Any computerized traffic system would have some bugs, and thus some deaths. But even if traffic deaths are reduced from 10,000 to 100, and likewise for injuries, the problem is that a computerized traffic system creates somebody else to blame, other than yourself and the other drivers. Lawsuits will seek out the vendors. Our current system depends on the fact that most people never get properly compensated, or that the compensation is spread out among thousands of drivers and their insurance companies. To concentrate it all in a few parties, even at a level orders of magnitude less, is probably more than any firm can bear.
People feel they are in control on the road.
Even if somebody else causes an accident, they like to feel they might have the power to avoid it with sharp driving. Tens of thousands of people are killed and more are injured by auto accidents, and this system could make a dramatic reduction in this. We have the technology now to do it, but we won't for some time because of fear of computers and litigation. Report problems with the web pages to the maintainer .
