Because you have to replicate the same complicated mechanism for all the cars. Moreover, if a gyro in one of cars malfunctions the whole train is at risk.
Another problem is that the system is reactive, meaning that there is a lot of shaking and balancing that is quite unacceptable - think about drinking a cup of tea in such a wobbly train even on straight lines, while on curves it's not staying horizontal by design.
Yet another problem is that it can't share the current infrastructure without major switch changes while sharing the infrastructure the other way around is impossible.
And in the end all of this effort for trying to fix a problem that doesn't really exist, at least not in Europe where most of the rail infrastructure was already built 100 years ago.
No wonder about the results. “The water tested was purchased in the U.S., Kenya, China, Brazil, India, Indonesia, Lebanon, Mexico and Thailand” - so basically just third world countries without strong food safety regulations.
This is the corporate disease. If everybody is following the procedures, then there is only one way - forward. Nobody can take a step back to analyse the current state, or admit that the company made mistake. Life goes on, the managers are taking their big bonuses, the engineers will continue to make useless inventions, and probably in few iterations a new keyboard will be announced, without admitting anything wrong with the current product.
TLDR; this whole article is a joke. The guy is not capable of extracting stats out of his nginx instance, so "Conclusion: Avoid nginx at all costs". End of article.
