4 self-driving cars arrive at an intersection...

(Kinda sounds like the opening line of a joke......)

But seriously, 4 self-driving cars arrive at a 4 way intersection at the same time.

Based on how they're programmed to proceed, which one goes first? It's my understanding that so far, self-driving cars have been programmed with a lot of patience and a tendency to yield the right of way to the other vehicle(s).

But if they're all programmed that way, will any of them make the first move? Might they have to play a virtual game of rock, paper, scissors? Maybe they announce each others VIN numbers, and the one with the lowest number goes first, etc.

Also, I'm really having fun with this online accident recreation software.....
