Why are you surprised?

At this point, it is a well-known failure mode of the Tesla Autopilot:

It does not notice tractor trailers. It does not notice street sweepers. It does not notice fire trucks. It does not notice lane barriers.

All happened in daylight, and in good conditions. The Autopilot just continues in high speed without even attempting to slow down - Controlled Flight Into Terrain.

Wired has a piece trying to explain why it cannot notice stationary objects [1].

It's like the joke about the dancing bear. We are impressed not by how well the bear dances, but by the fact it can dance at all.
