    Excessive lane changes during traffic jams will worsen traffic congestion!
  • For those who drive vehicles equipped with ACC (Adaptive Cruise Control)
    Use it in the driving lane! When traffic is congested, quickly follow the "Vehicle distance: short (S mode)" setting!
    ACC is a system in which a radar installed in front of the vehicle measures the distance to the preceding vehicle and maintains a constant distance according to the speed. There is a possibility that congestion can be alleviated by making good use of ACC.
