My apologies for starting a new AV thread but it seemed simpler.
The preliminary NTSB report into the crash in Tempe, Arizona where an Uber modified XC90 hit and killed a pedestrian pushing a bicycle has been published.
https://www.ntsb.gov...H010-prelim.pdf
The media reports suggested the Uber AV systems where not set up to recognise a pedestrian I don't think the report says that.
What it does say is that the AV system detected an object 6 seconds from impact but took until 1.3 seconds pre impact to determine emergency braking was needed.
What is rather weird is that "Uber had disabled the AV emergency braking to "to reduce the potential for erratic vehicle behavior. The vehicle operator is relied on to intervene and take action. The system is not designed to alert the operator"
For me two things stand out.
1) how long the system takes , albeit at night , to respond - 4.7 seconds - that's about 120 metres at 60 mph.
2) They relied totally on the permanent alertness of a driver who is basically not driving the car to actually initiate the emergency braking as the system gives no warning to her.
Any thoughts?
