How much deviation in straight-line driving is considered unqualified?

[Cruz]

In straight-line driving, the stability control of the driving direction is considered unqualified if the deviation angle of the vehicle's direction exceeds 10 degrees. Additional information is as follows: 1. Inverse ratio: During straight-line driving, the amount of steering wheel operation should be inversely proportional to the vehicle's speed. The faster the speed, the smaller the steering wheel operation should be, and the slower the steering wheel should be turned. 2. Driving: The vehicle should be driven in the center of the lane. On straight sections, try to find the feeling of driving on the right, left, or center to choose the appropriate driving position. 3. Principle: During straight-line driving, the steering wheel should be primarily controlled with the left hand, assisted by the right hand. Moreover, adhere to the principle of "timely correction, minimal turning and returning." If you feel the vehicle is deviating from the driving path, adjust the steering wheel as early as possible to correct it.
