I watched the video. You asked "why would they be taping the intersection", I gave you a pretty obvious explanation, not sure why you are so vehement about it.

I watched the video. You asked "why would they be taping the intersection", I gave you a pretty obvious explanation, not sure why you are so vehement about it. In turn, why would any sane person run a two ton piece of gear through a moving intersection, endangering pedestrians and cross traffic through a red light where it is known to have failed once already, not once, not twice more, but six times in a day? Why would you, as a responsible person, not immediately tell your test drivers to avoid this intersection until the issue is root caused, or, more likely, suspend testing for that day entirely? Or do you just assume every engineer at Uber is a cackling mad scientist blinded by their quest to create our new machine god?
