Mc Claren wants to replace the windshiel wipers with what jets use to keep windsields clean..................
SOUND!
Here's a quote from their artile:
"....McLaren, which wants to remove even the single wiper blade that clears droplets and debris off its expansive windshields in favor of a more high-tech solution. Its system, similar to those used on jet aircraft, would use an high-frequency ultrasonic transducer to clear the surface of the windshield, eliminating the need for a drag-producing wiper arm and blade – not to mention eliminating the weight of the motor as well."
Just keeping you in the loop like we do on all things automotive!
