Here's my algorithm: everyone drives "defensive" all the time. No new computers needed, and fewer "optimists" rear ending people.

  I like that idea, and I'd add it to mine: People drive at a constant speed. The root cause of traffic jams, in my opinion, is that people brake much quicker than they accelerate. This leads to traffic bunching up, and then stretching out as people regain speed. In the UK, the variable speed limits on major routes work if people obey them, as it cuts down this emergent behaviour.
