Makes me think that there is still a long way to go here. All of the changes they made to the signs leave them still easily readable by humans. One could see how reflections, weather and other environmental factors would distort a road sign more than this. Speed limit signs are possibly the hardest example though because it requires the system to recognise the exact number on it, rather than just its existence. I wonder how much harder it would be to get it to misclassify a stop sign?
