Automatic Emergency Steering

[joindy]

Some models have this feature. I thought sounded like a great option if you need to avoid car in front of you. But, after researching the details, I find it only engages if you are going under 50 mph, and your car will not leave its lane, so your car stays entirely in its lane, so unless car ahead is partially off the road, leaving space for your car to steer away slightly..but still stay your lane. This situation would be rare and unlikely to engage. The online videos demonstrating this feature, car you are approaching is primarily out of your lane and most of the car is off the road. Am I missing something here?
