What is the difference between second gear and reverse gear?

[MacAshley]

The difference between second gear and reverse gear lies in their different positions. Car owners need to pay attention to the positions of these two gears while driving. Below is a detailed introduction about car gears: 1. Speed range: First gear corresponds to a speed of 0-5km/h. Second gear corresponds to 5-20km/h, third gear to 20-40km/h, fourth gear to 40-60km/h, and fifth gear to 60-100km/h. 2. Gear shifting timing: Generally, the optimal time to shift gears is when the engine speed reaches 2000r/min, and should not exceed 2500r/min. For some high-displacement and high-power engines, shifting around 3000r/min is acceptable.
