Default To software guys - Do you have an idea of what is the Toyota software glitch?
"Software Glitch" Boy, that seems like a catch-all phrase. Do you guys who write code have any idea of what are the characteristics of this software glitch which causes Toyota Camrys to accelerate out of control? (I'm not a software engineer, thats why I'm asking)















Here are some of my guesses:















1. Other cables from noisy electronics which could be coupling noise into wires which go to the main CPU, causing incorrect sensor readings.















2. Code which isn't robust enough to recognize non-planned bytes. Like, if 11010001 (I made that up) means going forward while in reverse while the brake pedal is being pressed. The code writer thought, "that's stupid, that byte could NEVER occur so I'm not even going to worry about if that happens." and now we find out that it DOES happen.
