"approached the school bus from an angle where the flashing lights and stop sign were not visible"
I call bullshit on that. Yes the stop sign is only on the left side but the flashing lights are on all four corners of the bus. You'd need to be approaching the side of the bus from a direct right angle to not see the flashing lights.
Nah, if you want people to stop reliably the stop sign needs to be visible from all directions you care about. Just add it to the list of reasons why the roving random stop sign deployment solution for school buses is a bad one.
there have been increase of "aggressiveness" of autonomous cars. My earlier comment - https://news.ycombinator.com/item?id=45609139 . May be that aggressiveness is sold internally as some optimization enabled by the higher skills of the robot-driver.
