Re: Volvo admits its self-driving cars are confused by kangaroos
#42Lots of human drivers are confused by kangaroos and kangaroos are confused by cars especially at night. You see an awful lot dead kangaroos on the side of the road in rural Australia. As an aside, kangaroos in motion are one of the most efficient and elegant mammals. I love watching them bounding away at speed effortlessly dodging scrub and trees - more like flight than running.
Having had plenty of wallabies (smaller version of Kangaroos) jump out in front of me at dawn/dusk, I concur. The hopping movement makes it incredibly difficult to judge their speed and direction. They actually cover horizontal space at a far greater clip than they seem to, and also means they can make snap changes in their direction of travel VERY quickly, making any avoidance manoeuvre a bit of a wild guess.
Unpredictable motion is ideal for evading upright preditors with spears, but no so good for collision avoidance with fast moving metal objects.

What's the general feeling about taking the meat after a collision? Where I grew up, people would butcher the animal if it's not terribly destroyed. Around here there's a wild hog problem, which are edible but not very tasty, so the local wildlife agency picks them up and they're used in soup kitchens to feed the homeless.

#45Earlier quoted context omitted.
>> You need actual distances to objects, not just fuzzy error-prone inferences. Humans do pretty good with fuzzy notions of where the animal is. Exact distances aren't needed so much as reasonable estimates. If it is probably in the "need to brake zone" then the car brakes. Plus or minus a few meters isn't a big deal so long as you've got margins to work with. As animals are unpredictable, Volvo certainly has wide ma…
But apparently humans get confused by kangaroos too, based on the number of collisions.

#48Those corner cases can be solved by simulation. Off to the sims, to implement kangaroos, deer and people in wheelchairs chasing ducks with a broomstick - just to be thorough.

This was in an environment where daytime temperatures are often 40C (104F) plus during the day.
