Given the current reliability of classic wiper systems I don't think this is the improvement. Part of the reasons classic wipers have multiple moving parts (basically motor + rack and pinion) is that you want to guarantee they stay in sync and never overlap. You can put 2 simple motors on them for similar effect like the Tesla design. Tesla's solution focuses on design rather than better technical specs. The claim that "the electromagnetic moving block induces minimal friction" says very little considering you achieve the exact same effect with a classic wiper arm mounted on a single electric motor. You probably want more than one arm anyway.
