I think the immediate aftermath of an unsignaled lane change is the worst time for the car to automatically cutting from presumably highway speeds of like 65-70 mph (105-113 kph) [assuming they weren’t speeding…] down to 31 mph (50 kph) if there are people driving in the new lane. Not only did someone pull out in front of you but you also have to immediately slam on the brakes to have a chance of not hitting it
