Sure, we have intermittent settings and rain-sensing and Mercedes had that bonkers Monoblade, but the concept hasn’t changed much since 1903. According to a patent filed in March and published just five days ago though, the reign of the single-pivot wiper may be in trouble, as Tesla has a new idea. A wiper idea.
