Why doesn't the chassis scrape when going uphill diagonally?

[DiAndres]

Temporarily increases the ground clearance of the front and rear axles. More details are as follows: Reducing undercarriage scraping: Generally, cars have a certain amount of ground clearance, which is the distance between the chassis and the road surface. If the ground clearance is not high, it is easy to scrape the chassis when going uphill or downhill. Going uphill diagonally can reduce the uphill angle and minimize the occurrence of undercarriage scraping. Steep slopes: When encountering steep slopes or non-standard speed bumps, if you are not confident about the vehicle's ground clearance, you can choose to go uphill diagonally. This allows the vehicle to align sideways with the uphill road surface as much as possible. Once the front and rear axles have successfully passed, you can straighten the vehicle. This reduces the risk of scraping the front lip due to insufficient approach angle and also minimizes the risk of the rear axle being too long and scraping the underside due to insufficient angle when going uphill.
