You may have seen the bird, But have you thought of what a high speed lane change may have done to him, the car, and other motorists on the road. Have you ever Attempted a unplanned lane change at high speeds, He could and probably would have sustained far more damage than that to the car, and possibly killed himself and probably others on the road. Kinda like people that swerve unexpactantly to avoid a squirrel on the road and end up killing themselves. Granted the bird could have got him. But in this case he did the right thing.
