I was actually curious about this so I started looking into it, this article doesn't do it justice. Most articles on it give a better clarification of how the intersection was laid out.

The vehicle definitely didn't gun it to race through the intersection it started moving as soon as it was clear that the truck entering the intersection was going straight and not turning, however the cyclist who was behind it didn't stop at the intersection like the truck did and continued following behind the vehicle until deciding to blindly turn left.

I really don't think that was the fault of the machine and I think a human driver would have done the same thing and are really might not have stopped in time. I think this is a clear no-fault or cyclist fault because the machine followed road laws, I'm not sure why these cyclist would decide to blindly turn left in a four-way intersection knowing that in a four-way intersection the opposite side can go at the same time
