Should the dry dual-clutch transmission be shifted to N gear when waiting at a red light?

If the waiting time is within 30 seconds, it is recommended to stay in D gear and apply the brakes; if the waiting time is between 30 seconds and one minute, shift to N gear and engage the handbrake. Whether to shift to N gear at a red light depends on the waiting time: 1. Waiting time within 30 seconds: If the waiting time is within 30 seconds, it is recommended to stay in D gear and apply the brakes. Since the time is short, shifting back and forth is more troublesome, and frequent shifting operations will increase wear on the clutch and transmission. 2. Waiting time between 30 seconds and one minute: If the waiting time is between 30 seconds and one minute, it is necessary to shift to N gear and engage the handbrake. This operation can disconnect the power transmission, reduce engine load, and decrease fuel consumption.
