First, correct the landlord. You must be talking about the first button in the driver's seat. It is EspOFF, which is used to shut down ESP, that is, the body safety and stability system. It is recommended not to press. Turning off ESP means that the landlord doesn't want ESP to intervene when he starts faster or drifts compared with others, which will affect the performance when playing with cars. ESP intervention will limit the vehicle to a very conservative state. For example, in the starting race, ESP will limit the power output of the engine, so that the front wheels can never spin, which will affect the starting speed.
