Highway speeds are fast, so the distance between vehicles should be increased. At a speed of 100 km/h, the wheels travel about 28 meters in one second.

Tip: Tailgating accidents are common on highways due to unfamiliar roads, slow driving, or sudden stops, and most often occur near exits.

The selected transmission must match the engine's installation dimensions. There are four considerations: the transmission's output shaft diameter must match the clutch disc's inner diameter; the clutch specifications must be compatible with the clutch housing on the transmission; the engine's clutch housing holes come in two sizes, 12~10.8mm and Φ12~12.5mm, so attention must be given when choosing a transmission; engines of the same level may have different designs for the clutch transmission's front bearing position by different manufacturers, so the transmission's output shaft length (i.e., shaft extension) will also vary accordingly.

Tip: Before you leave, make sure to thoroughly inspect all four tires, and have them properly adjusted at a professional repair shop for tire pressure. Especially don't forget to check the spare tire to ensure it's intact and inflated. While taking breaks along the way, inspect the tires by tapping them with your fist to check for normality. If there's a leak, repair it immediately.
