The tesla did not consistently detect that the thing infront of it was a truck, so it didn't brake. Also, this describes a lot of similar cases.
I remember a youtuber doing similar tests, where they'd try to run over a fake pedestrian crossing or standing in the road at low speed, and then high speed. It would often stop at low speed, but very rarely stopped or swerved at high speed.
