I'd like to see the actual data it gathered as well. Plus, I'd like to see the software system, ML models, etc - to run the data against.
The dash cam video is very suspicious. What I want to see is the actual computer vision camera footage; it's never been made clear whether the footage that has been publically made available is from a dashcam or CV camera; I suspect the former.
On the notion of the LIDAR - the device spits out 64 beams; it appeared in the video the woman who was hit was wearing a fuzzy and dark color jacket (was she? I don't know for certain). If this is so - it is possible that any reflections for the LIDAR returns only came from the bottom half and the bicycle at best. The top half would have been either absorbed, or possibly filtered as "noise" prior to the classification algorithm.
Which is why the ML algo's matter - how did the classifier classify the data? Did it think what was moving across the road was something other than a human? Without the data and the algorithm, there's no good way to know.
But now I hear it's possible the LIDAR was turned off to run a "vision only" driving system. Was it? Who knows; we may never get the truth of what happened here.
Form a personal standpoint, it saddens and perplexes me - and makes me upset to a degree - that this happened here in my city. I recently completed the Udacity Self-Driving Car Engineer nanodegree, and I tend to wonder if this incident will somehow potentially color any future employment opportunities in that field, should I pursue them...
The whole political angle of this thing - sigh.
- andrewla 9y agoThe software system and ML models would only be necessary if an analysis of the underlying data showed that there should be a reasonable chance of avoiding the accident. If that were the case then the models and training process could well be distinction between simple recklessness and gross negligence. I doubt the LIDAR data would be that useful compared to the enhanced high fidelity video just because of how interpretable it would be to a jury.
