🚥 Signal Sync
One intersection, four queues, one signal box under your thumb. Flip the lights, keep the cars flowing, and never let two directions meet in the middle.

Tips & Strategy
- Switch early, not late. Change the light when the green queue is nearly empty, not after it is — cars need a beat to clear the box.
- Watch both stop lines. The queue you can't see on screen edge is the one that will crash you.
- Don't panic-flip. Every flip wastes green time for both directions. Two good switches a wave beat six nervous ones.
- Ride the rush hours. Spawn rate comes in waves — hold a direction through a lull and save your flips for the burst.
