Convert to 100% smart traffic signals

If we will soon have cars that can see everything around them, why can't we have traffic signals that can count cars at an intersection?

Within a decade or so, there will be cars that can go on any road, recognize traffic signals, warning signs, pedestrians, other cars, etc. Imagine one of these cars stopping for a red light when there are no cars coming from any direction. Or how about when traffic in one direction is backed up for hundreds of cars going one way when there are hardly any cars going the other way? Installing truly interconnected smart traffic signals with artificial intelligence on every intersection in the city would probably cost a fraction of what it would cost for a major upgrade to any of the City's existing primary roads. I've heard City officials state that the traffic signals downtown are synchronized, but compared with driving in cities where they really are synced, I have my doubts. This is something that should have been done 10 years ago. For a City that believes it is advanced, this upgrade is long overdue.
