One Calm Car

There is no crash and no bottleneck. A delayed stop–start wave is circulating anyway. You are the gold car. Use gentle acceleration and braking to absorb it without compressing any headway. Quiet variance must hold for seven seconds; emergency spacing ends the experiment.

GOLD CAR · your acceleration
