Did they have to consider people dropping phones out of car windows (or off a boat ?) What about ski crashes or skateboard crashes?
I'm cognizant of the 80/20 rule, and "perfect is the enemy of good," but if a run-of-the-mill coaster is setting off that detection, then I'd wager the traveling fair rides will be even more violent, based on my experiences growing up
I have no idea where this falls on the privacy spectrum, but I'd guess if there are 5 or 10 triggering events within some timespan and some geo boundary, that's an indicator of a themepark-ish setup
Clicking "report false positive" on the phone would also likely go a long way
It's the hubris of tech people to think everything can be solved (or made better) with technology.
It is obvious to me that these decisions will become more and more difficult. I am certain that at some point (not sure if 10 years from now or 50) driverless tech will be safer than people--by a margin of say 99%. I am equally certain that this will be accompanied by a set of accidents unique to the driverless tech. I think of it as similar to compilers. When I started programming PCs assembly was always king. C got better and better. 10 years into my career C was mostly better. Now C/C++/Rust etc. almost never need code rewritten in ASM.
a phone in your pocket does not have that context.
