Why does the car move forward instead of reversing on a steep slope?

[DiZoey]

R gear is the reverse gear. As long as the handbrake is not engaged or the brake pedal is not pressed, and the car is running, it will inevitably roll forward or backward according to the characteristics of physical inertia. Here are the relevant details: Introduction: For front-wheel steering vehicles, the driving trajectory is more sensitive to the steering wheel when reversing. Slightly turning the steering wheel too much will cause the front of the car to swing outward, and there is even a risk of overturning. There are often videos online of off-road vehicles losing control and overturning when reversing after failing to climb a slope, mainly due to excessive steering corrections at high speeds while moving backward. Precautions: If the speed is too high, the braking distance becomes longer, which is unsafe. Moreover, at high speeds, the ABS is more likely to activate when braking. On roads with insufficient traction, if the ABS is triggered, it can be quite terrifying, as the braking system may enter a deadlock state.
