from selfdrive.car.interfaces import CarInterfaceBase class RacingCarInterface(CarInterfaceBase): def __init__(self): self.params = self.get_std_params('CUSTOM_CAR') self.params['max_speed'] = 200 self.params['acceleration'] = 1.5 def get_params(self): return self.paramsIn this example, we create a new class named RacingCarInterface that inherits from the CarInterfaceBase class. In the constructor, we call the get_std_params method with the argument 'CUSTOM_CAR' to retrieve the default parameters for a custom self-driving car. We then modify the 'max_speed' and 'acceleration' parameters to optimize performance for a racetrack. We store the modified parameters in the self.params variable, and provide a method named get_params that returns these parameters.
