Good thing, then, that a team out of Saarland University in Germany has devised a wireless braking system that does away with those protruding brake levers and messy wires altogether. What's more, the mathematical calculations the team applied to determine safety--the same used in control systems for aircraft or chemical factories--deem the brake 99.999999999997 percent reliable.… Read more
