As a developer using Microsoft tools, I'll take the "Hippocratic oath for software engineers" when Microsoft releases fully bug-free tools and operating systems. Not until then.
Gyroscopes accumulate error with time, they make sense for an application with a short range but they're useless over long periods of time without a reference standard to crosscheck and recalibrate. That's one part of The Martian the author got entirely correct despite the criticism. The mechanical odometer in your car is only accurate to +/-3% of reading and the best mechanical calibration standards are only 0.25% of reading, that puts the trip described in The Martian off by ~90km.
NASA has the brains to design a better odometer but navigating by stars and GPS makes more sense.
Also, remember the +/-3% next time you're comparing a used cars. Worrying about 5-6,000 miles on a car with 100,000 is pointless since the odometer itself lies by up to 3,000 miles. Then you have further error introduced by new sets of tires which wear down 6-15mm depending on their tread depth and can vary several mm in diameter despite having the same nominal size as the OEM tires.
Actually, Europeans can be jerks and aholes as much as Americans. I'm speaking from personal experience. Given half a chance, as they were on the project that I'm working on, the Europeans behaved identically, perhaps worse, to Americans. If the stakes are right (promotion and $$$) and the opportunity presents itself, just about anybody can be a jerk and get away with it. Sorry if the truth hurts.
