> You are also doing object recognition.

Object recognition has been a part of autonomous driving systems for a very long time. The difference between a stroller and a piece of paper is pretty well understood by these systems.

The answer is to always keep a large safety margin between you and the vehicle in front of you when traveling at high speeds, so you have time to react and take the safest course of action. Seconds make a huge difference in this scenario and it's easy to get them. No autonomous system is going to be hugging a truck bumper, but rather is going to always maintain a significantly greater safety distance than an aggressive human driver would.

You can never be sure that the box is empty, so I'd recommend always swerving to avoid.
