Germany's Self-Driving Streetcar Puts Autonomous Tech on Track

Of the many acronyms engineers spend their lives internalizing, few are more valuable than KISS: Keep It Simple, Stupid. Constrain the problem, reduce the variables, and make life as easy as possible when designing novel systems—like, say, a self-driving car. The world is a messy, complicated place. The less of it you need to solve, the closer you are to having a working product.
