She crossed at a spot that was pitch black. Sneakers come into view maybe 40 feet away. Clearly visible at 20. Is that enough time to stop at that speed? Not sure I would have stopped in time.


You don’t need to stop. Slowing from 40 to 30mph decreases the fatality rate by an order of magnitude. Maybe the car shouldn’t have been going above the speed limit if the conditions were so poor that it couldn’t plausibly see humans walking right in front of it.


That's an argument intended only to shift blame and distract. The car was going 38 in a 35 which is well within the legal margin of error on a speedometer[1]. For all we know, the speedometer read exactly 35.

There's enough blame to go around between the driver who was obviously texting and the woman illegally jaywalking, you don't need to invent a false controversy.

I recall reading that the speed guns where I am from have a tolerance of 5 km/h or 5%, whichever is greater.

3 mph is beyond the margin for error, you'd get fined for driving that quickly.


I mean... I even provided a source and everything. And you threw that all away with a glib "nah I read somewhere that you're wrong".

Please read the link. I may still be wrong, but by my math, the car was a Volvo XC90 which means the acceptable margin of error on the speedometer is +/- 3 miles per hour.


Our points are complementary. The errors of the speedometer and the error of speed gun may add up.

The police will take off 5 km/h on the recorded speed, when editing the fine. That's supposed to cover the margin for error.

You're out of luck if your car meter is 5 km/h off and you were trying to drive at the speed limit.


Nice try, but these cars have GPS. Trying to evenly pin the blame for the pedestrian’s death on her is insane. Talk about trying to “shift blame and distract.”


Speed limits are for optimal conditions. Night driving is not optimal so the vehicle was going too fast.


Exactly. Humans could have swerved or slowed down at least some in time to lessen the impact.

If you replayed the exact scenario the chance of the same outcome is likely absurdly high with the robocar. If you replayed it with the same human it would likely be much better. If you replayed it but varied the human driver, maybe even better than that.


Was it going above the speed limit?


It was reported to be going 38mph in a 35mph zone.


The report was wrong. It is a 45 mph zone.


How fast was the car going?


It seems pitch black on a video, but human vision is much better in low light. You may have had way more time to react.


only person who bothered to point this out. A camera from the car doesn't even give the picture a human would see or what a million other sensors would see.


a human would have attempted to at least move to the left to avoid a collision; specially since she had a very visible bike with her.
