Pretty much every critical system in a vanilla Toyota is already software-controlled, not to mention the legion of critical systems involved in air travel, elevators, medical equipment (e.g., pacemakers), etc. Not sure that this should bring comfort, but at least you need not be particularly frightened by your Tesla. :)

- darkerside 8y agoAren't brakes and steering mostly manual? I don't think it's the right advice to tell people to trust Autopilot when it's failed in several egregious ways.
- TylerE 8y agoSteering is electronic.
- jgibson 8y agoElectronically assisted, but still mechanically coupled for 99% of consumer cars. I've completely lost 12V on a car before and still managed to bring it safely to the side of the road. Inifinity tried steer-by-wire but ended up retrofitting traditional hydraulic steering back.[1] [1] https://en.wikipedia.org/wiki/Drive_by_wire https://en.wikipedia.org/wiki/Drive_by_wire
- chii 8y agosterring is electric, but there's always a backup system in case the electronics fail: https://youtu.be/em1O8mz7sF0?t=276 https://youtu.be/em1O8mz7sF0?t=276
- jgibson 8y agoThey are manual in the sense that there is a physical connection: the steering wheel is usually mechanically coupled with the steering rack, brakes usually through through hydraulics. That said there are probably 5-20 systems in a car that can completely control these systems without any human input. Think of automatic emergency braking, traction control, vehicle stability control for the brakes, and autopark + powered steering for the steering. Most of these systems have multiple redundancy and isolated monitors (eg, if autopark is on and the vehicle speed is > 10mph, the monitor will intervene) but there are still probably some theoretical situations where this could occur
- mhh__ 8y agoDriving a car on the road with other cars is - factoring in the age of the tech, lack of regulation, involvement of humans and the consequences if it goes wrong - more difficult that what's mentioned on your list.
- Retric 8y agoElevators use simple physical safety systems. Which is why you see headlines like: "Skyscraper elevator plunges 84 floors — and everyone survives" https://www.cbc.ca/news/world/elevator-plunge-chicago-1.4913707 https://www.cbc.ca/news/world/elevator-plunge-chicago-1.4913...
- bleomycin 8y agoEvery link i’ve seen to this story annoys the hell out of me because they don’t explain HOW the elevator eventually stopped. That’s literally all I want to know.
- CydeWeys 8y agoIt reached the bottom. Probably hit one of these: http://elevation.wikia.com/wiki/Buffers http://elevation.wikia.com/wiki/Buffers Note that it wasn't descending particularly quickly; one cable snapped but other safety systems were still operable.
- vvillena 8y agoThe article says it went from the 95th to the 11th floor. It appears it stopped before reaching the bottom buffer.
- gonzo 8y agoEntering “elevator safety mechanism” into google will bring up several links with explainations. The first link for me references this story.
- nsxwolf 8y agoI’d also like to know what they meant by “plunges”. How fast did it descend? Was it in free fall?
- thaumasiotes 8y agoYou can easily tell that it wasn't in free fall, because if it fell 84 floors in free fall and then stopped, the passengers would have died.
- foobiekr 8y agothere's a huge complexity difference, however.
