The update is pretty useless!
It gives two copletely oposite things the car WILL do if it can without specifiying what it will do if both options are possible.
Also there is a big inconsistency in the story: statements say the light changed to amber as it entered but it seems the other lanes had already stopped - why? unless the light had changed much earlier. Congestion is one posibility I suppose but in that case how was the robo car doing nearly 40mph.
I presume the other lanes had stopped othewise the other car would have not tunred in front of them or would have hit them instead.
