I see it as indicating a need to revise definitions. Ultimately what we want is a car that is at least as good as driving itself as we are at driving it. But even the Eyeball Mk. I is unreliable if the rain or snow is heavy enough. I've often had to simply pull off the road in a torrential downpour and wait it out. Why isn't this be the watermark for full autonomy- a system that recognizes when the SNR is too low to proceed, and suspends itself safely?

There will always be a set of conditions that overwhelm your sensors. It sounds like the definition is bad. but we can probably develop an autonomous car that is satisfactory nevertheless.
