"ignorance is bliss"
If you knew how much software went into a car vs. an airplane, you might think twice. Airplanes seem more complicated than cars, but software-wise they are much simpler. Cars have millions upon millions more SLOC than airplanes. You think MCAS is bad, how about cars that have sudden loss of steering, emergency brakes that mysteriously engage, or a throttle that can't be disengaged?
Serious design flaws in airplanes are these big dramatic events. Serious design flaws in cars pop up in the news every day, and we just ignore them [1][2].

- CydeWeys 7y agoSoftware flaws in cars are not nearly so catastrophic.
- umvi 7y agoCatastrophic as in 300 people will not die due to the flaw, yes. But one-off car fatalities that kill 1-3 people happen regularly and they add up. The self-driving variety pop up with the highest visibility but if you go searching you'll find tons of accidents where brake failure at highway speeds cause a fatal crash. I do concede that distracted driving and alcohol play a much bigger role in the large amount of car fatalities than software flaws. But I still stand by my original assertion that you are more likely to die due to the effects of a software flaw in your car than due to a software flaw in the 737 Max.
- CydeWeys 7y agoHow do software flaws in cars kill you exactly? The main example you bring up is brake failure at high speed, but that's not a software issue, that's a mechanical issue (and is oftentimes caused by neglecting maintenance on the part of the car owner). Yes, there's the self-driving stuff, and there have been some egregious examples, but those systems also save lives by preventing accidents. Lane departure warnings, automatic braking, and electronic stability control all, on the balance of things, make driving much safer.
- ulfw 7y agoOnly a heavy-software run car might (e.g. a Tesla autopilot or the Uber fatality). But I agree with you. I fail to see how software bug in a car would lead to a comparable outcome.
- bumby 7y agoI don’t think most people realize how software dependent their “dumb” car is. From antilock braking to throttle response to steering response in some cases is largely controlled by software. It goes way beyond the infotainment systems we intuitively think of as software
- kube-system 7y agoElectronically controlled throttles have been on the road for over 30 years now, and became extremely common in the mid 2000s.
- umvi 7y agoI agree that cars are more safe now than ever before and that mechanical failure is more deadly than software failure. The whole point of my comment was to put to bed the irrational fear of flying. You are still more safe travelling long distances in a faulty flight system such as the MAX than you are by car. There are just too variables to account for in cars, one of which includes increased software complexity.
- CydeWeys 7y agoThe 737 MAX crashed twice and killed 346 people. It's not an "irrational fear" to refuse to ever fly in one again. Secondly, what are the exact figures you're using to show that the 737 MAX is safer than cars? And now compare it to other planes, the more realistic comparison? I'm not taking planes to places that are within driving distance. The 737 MAX was waaaay less safe than other planes.
- bumby 7y agoI think we have to stop segmenting our thoughts into “software” and “hardware” and instead look at issues like the 737 Max as an integrated system failure. “Software” failures can easily manifest themselves into hardware failures; thinking of them as separate systems can lead to a complacency mindset of “its just software so we don’t have to be as rigorous in our design”

- HarryHirsch 7y agoThe Takata airbag issue wasn't ignored at all, it was a very serious safety issue. For defects of that magnitude there's the Department of Transportation, and there will be recalls to pull the faulty part out of circulation.
- magduf 7y agoSoftware flaws in cars usually aren't fatal. If your car has a failure, you just pull over on the side of the road. You can't do that in an airplane. >how about cars that have sudden loss of steering Citation needed. I've never heard of a car having this problem, and it's generally impossible because there's a mechanical link between the steering wheel and the front wheels. >or a throttle that can't be disengaged? Citation needed. I've never heard of this happening where it's been proven to be real and not a publicity stunt. All the problems with "unintended acceleration", including on Toyotas a while back, have been shown to either be people using aftermarket carpet mats, or even people faking it. What's more, turning off the car in an emergency is not hard, even in push-button-start cars. Now of course, we can blame some wrecks from faulty systems on poor driver training, drivers who just aren't very good, drivers who can't handle an emergency, etc. This simply does not apply in an airplane: pilots go through a LOT of training to get that job, so if they crash anyway, that points to an unforgivable mistake in engineering or manufacturing.

- asynchronous13 7y agoTo be fair, "sudden loss of steering" is different than "sudden loss of power-assisted steering".
