The first point lands when this generation ends.
One point per generation. A hundred and twenty cars drive the same fresh traffic at once until they are all out or fifty-five seconds pass, then the best are bred into the next hundred and twenty. The solid car is whichever is leading; the faint ones are its rivals.
Five lanes, seventeen sensors, seven kinds of traffic
Every car here steers itself with a small neural network, reading distance from seventeen rays and its own place in the lanes. There is no map and no route. The pack starts from a driver trained in advance; set it back to a blank slate in Settings to watch one work it out from random weights. Traffic is dealt fresh every generation, so memorising one road gets you nowhere.
Space pauses. R starts over. 1–4 change camera. Arrow keys drive.
