Even if it doesn't move its arms like a prototypical walking human, shouldn't the car still stop, rather than ram into an unidentified large obstacle / skateboa

Even if it doesn't move its arms like a prototypical walking human, shouldn't the car still stop, rather than ram into an unidentified large obstacle / skateboarder / pedestrian carrying something? If it's driving in a parking lot rather than a busy city street, shouldn't that have meant it can also safely swerve away from the obstacle in almost any direction?
