Eliminating automobile windshield wipers

P1_shanghai_street_v006_pearl_white_v4McLaren is talking about applying some military grade fighter jet technology to their road cars to eliminate the need for windshield wipers.  The system would use a high frequency (~30kHz ultrasonic) transducer to repel water, insects, even snow and ice.  It’s hard to say how serious they are…but when you look at the technology in their latest road cars the 12C and the P1, this isn’t quite as far-fetched as it might sound.  The biggest challenge might be making this technology street-legal…windshield wipers are currently a requirement, and car companies have a hard time bringing new technologies to the road (adaptive headlights, for example).  (via The Sunday Times)
