One advance I was particularly pleased with was a sensor that automatically detects low air pressure in my tires. It is sometimes hard to tell by looking at a tire if its pressure is low, and checking tires manually is a dirty job, so I did it infrequently. A continuous test of tire pressure was, I thought, a tremendous invention.

During the same period in which car manufacturers invented ways to test tire pressure continuously, software development teams learned that testing their products continuously was also ...
