Twinlane Courier
Drive two couriers through six synchronized checkpoints. Every Left, Right or Coast advances one beat. In MIRROR gear, the upper courier follows your steering while the lower moves the opposite way. In PARALLEL gear, both move the same way. You have only TWO gear changes; changing gear does not advance time. After beat 2 both must align at column 2 to exchange parcels. After beat 4 the upper must scan column 4 and the lower column 2. Finish beat 6 with upper at column 5 and lower at column 1. Red cells forecast the current beat’s barriers on each road. Neither courier may leave the road or land on its barrier. Plan the shared steering, not each car independently.
