Tragic about the cat - and Waymo must improve - but we cannot lose sight of the greater good.
I can't find anything saying waymo has a thermal camera. They aren't expensive- certainly not compared to the LIDAR- and provide extremely discriminated input on "am I about to kill something?" They're not perfect as foul weather and fog are likely to blind thermal- but they shouldn't be driving in suboptimal conditions until they have a track record of safety in optimal ones.
To be clear, I don't blame the witness for not doing this in the moment. And she probably has figured this out by now, too. I'm mostly pointing out that, as more and more people learn about robot taxis, more people will known how to help in such a situation, which is clearly what she wanted to do.
(It then proceeded to drop me off in a weird back corner spot in Santana Row by a loading dock. Can't have everything.)
I assume once you're close enough or actually under it there's a blind spot. It doesn't seem very good at evading potholes either.
