Kangaroos are a thing now!
While avoiding kangaroos on the road last night, I happened to look down at the visualisation and for the first time (must be part of the new visualisation in 14.3), they are actually displayed on the screen now.
Well, they don't look like kangaroos, of course. They have 4 legs and walk like dogs. They kind of look like dogs too. Or small deer. They seem to have long legs. Couldn't tell if it was trying to display a large dog or a small deer. I didn't get time to take a photo unfortunately, they hopped away (according to the screen they ran away).
Anyway, that now gives me hope that the car may actually try to avoid one if on Autopilot. Of course, I never use autopilot on that road, but it's comforting that it is actually recognising them as animals, so may do something useful (like stop) if it sees one ahead. Up until now I have just assumed it would ignore them and just plough straight through them like it does with potholes.
