What are the ways to prevent the car from slipping?

The methods to prevent slipping are as follows: 1. Change the brake pedal with your left foot and step on the accelerator with your right foot. When the vehicle speed is increased above 3000, the left foot will step on the brake and basically will not slip. However, because the foot brake brakes four wheels at the same time, the driving wheel is locked and the accelerator is pressed at the same time, which may theoretically damage the gear of the gearbox. 2. Pull the handbrake, loosen the foot brake refueling door, and increase it to a certain speed to start the handbrake. This is similar to the starting principle of hand brake on a half slope. Because the handbrake locks the rear wheel, it should not damage the gearbox. 3. Hover, completely release the throttle before approaching the toll booth, but don't step on the brakes. When the forward force of the vehicle completely disappears, slowly refuel the door. At this time, the tension under gravity and the engine power are in a state of balance, and the vehicle can completely stop on the slope without stepping on the brakes and handbrake. When the toll is paid, just step on the gas pedal, and you don't have to brake at all. This operation method requires high throttle control of the driver.
