Driving can easily end up as a competitive game where safety is traded against efficiency. The big versions of this are terrible, assholes weaving in and out of lanes at +20 mph. But it happens in little ways too, the rolling stops at 4-ways from the article are probably a tiny example.<p>Someone should host a programming competition where every entrant writes the AI for a fleet of simulated driverless cars, each with random starting and ending destinations. Collisions mean you instantly lose. Your score is based on how quickly you can get through traffic generated by all the other AIs.<p>I think the results would tell us a lot about where things are heading, or maybe where they should or shouldn&#x27;t be allowed to go.<p>(Of course, if you could control the whole fleet, all the cars could just ignore all the rules and dodge each other while tearing through intersections.)
