there are plenty of traffic situations in which you need on demand access to a lot of power to prevent an accident

President Beep posted:one of the wheels will be lower than the others so that when you push down on one corner the other pops up. this is not a problem if you use Apple Roads Pro™, which are designed with only left turns, the curvature perfectly matching the carefully optimized asymmetry of the Apple Lomarf Car™ suspension for a superior driving experience. We think you're going to love it.

the toyota software was buggy yes but the loop also would reset when the brake pedal was released. in order to get stuck in unintended acceleration mode, the driver had to floor the brakes and keep them held through the entire event. one pump and it would be over (in fact that's what your girlfriend was complaining about the other night). the people who had these horror experiences pushed the pedal to the floor and didn't let go, didn't try to put the vehicle in neutral, and didn't think to shut the engine off. so you can at least partially blame brain lockup. also not the same incident but apparently something like half of all cases of irreproducible "brake failure" turn out to be either floor mats bunching up or women kicking off their shoes and having them roll under the pedal.

Fuzzy Mammal posted:haha oh man I don't think that's from the actual source code, but just an example of the kind of stuff NASA/JPL's code verification tools explicitly check for. One fun thing is that many functions were hundreds of lines long, with the largest being 740 loc excluding empty lines and comments.

one time a guy ran a red light way too late and my mom was first coming from the other direction. normally shes a terrible and careless driver but something in her brain snapped and she floored it and swung around him

hell, just speeding up to pass somebody on the highway is a common example of needing an extra burst of speed for safety

President Beep posted:install war emergency power in cars, imo. it's already there for most people, called "the upper half of the tachometer" people are so scared to use full throttle that cars are mapped now with like a logarithmic scale on the gas pedal where 80% of the throttle is in the first third of the travel. cause otherwise they tiptoe it and complain that the car doesn't have any power. idiots
