So basically they modified a 35MHP street sign to make it look like a 85MPH.
I looked at it from a distance, and it was hard to tell between 35 and 85.
So if it is hard for a human, then it seems obvious that a tesla would also fail to recognize a 35.
Maybe the difference is that a human might not be certain and slow down just in case, whereas a deep neural network might be certain in its errors.
- tmpz22 7y agoA human has the basic intuition to assume the sign itself might be wrong or misleading, the programmers of the car automation failed to realize that in a way that might've gotten someone killed.
- russfink 7y agoGood thing, too, that nobody stepped out in front of their car, like a kid chasing a ball, as they did their ad hoc experiment.
- frosted-flakes 7y agoThey didn't allow the car to reach 85 m/h, for obvious reasons.
- pathartl 7y agoThere's several factors they could use to bring a level of uncertainty to the algorithm. Compare against the previously clocked speed limit, compare against map data, compare against the speed of other vehicles in a proximity, judge based on density of crosswalks, parked cars, traffic, etc. This isn't a failure of autonomy imo. Speed limits are arbitrary placeholders that are more for supplementing the slow reaction speed of the human brain. If we started focusing more on making the algorithm implement actual analysis of the environment instead of "the rules of the road", we might see better results.

You need to be a special type of stupid to think that a road with a speed limit of 35 MPH is 85 because of a road sign. The 'drive into the lake because the GPS nav tells me to' level of stupid.
