Hard to say. The assumption is a human would be seeing the same thing as the image from the camera. We don't know if the picture we are seeing is from a dash cam, most of which aren't that good at night, or one of the guidance cameras which should be much better.

I find it kind of scary how hard it is to see pedestrians who are off to the side when I'm driving down dark roads, especially if they're wearing dark clothing. I would not know if someone was standing at the side of the road if my headlights didn't play upon them, and if they suddenly moved out into the road (why the **** did she move out into the road in front of the car?) I would not have noticed before she got in front of me and the headlights picked her out.

especially on (semi) rural roads without any street lighting, and add in some rain.

I agree, not only pedestrians but cyclists with no lights or reflectors. Most cyclists try to light themselves up with LED's and reflective clothing but there are still a lot of idiots out there.

One thing autonomous vehicles will be able to do in future is communicate with each other to avoid contact. That won't solve the pedestrian, cyclist problem though

If you are doing 50 kph, see an object in front of you and it takes 1 second to react, you will travel 14 meters before your foot hits the brake pedal.

I finally watched the video, here are my thoughts.

  • It appears the main video of the roadway (bottom right) is either a dashcam, or one mounted high up like a dashcam.
  • The video on the bottom left appears to be aimed at oncoming traffic so doesn't catch the pedestrian until too late. It appears to have the best quality for analyzing what is going on from a software standpoint.
  • I can't make out anything on the video at top right other than lamp bulbs, was it supposed to be aimed so high?
  • If the video is in real-time and 30fps, then I estimate the car is doing about 40mph (65kph) based on how many frames between white lines. If I had the raw video it would be better, because who knows how many times it has been manipulated (not maliciously, but simply running through video editing software) before being posted to youtube.
  • The headlights appear to illuminate only about 75' in front of the car, where federal regulation say it should be 150-200' (high beams 250-350'). Arizona has some strange regulation about lights higher than 300 candlepower can’t illuminate more than 75 feet in front of the vehicle but I am not sure if that is headlamps or special utility lamps.
  • The pedestrian did not 'jump' out in front of the car, she was crossing the road. It is hard to tell, but at the last minute it appears she increased her stride to get out of the way.
  • The driver did not react until 1/2 second after I see the pedestrian's shoes, and another 1/2 second before you see his expression change. Was his initial reaction (slight movement of eyes) to the pedestrian or to the car breaking or something.
  • I suspect there is a lot more raw and processed data that is available that we have not seen.

Researchers Trick Tesla to Drive into Oncoming Traffic

By painting 3 triangles on the road!

Steering a Tesla car off the normal driving lane, potentially on a collision path, is possible without hacking the vehicle's advanced driver-assistance system, better known as the Enhanced Autopilot.

By painting interference patches on the road, researchers demonstrated that a Tesla Model S 75 can follow a fake path without asking the driver for permission, as the Autopilot component does in the case of changing lanes.
