Supercar designers McLaren are working on secret plans to replace the rubber wiper with a hi-tech ultrasound device that stops anything sticking to the windscreen.
Adapted from a similar system used on fighter jets, the proposed design is understood to centre on high frequency sound waves that effective create a force field across the windscreen preventing water, insects and mud from resting on the glass.
It would create tiny vibrations outside the range of human hearing that shake off anything debris that comes near.
Sound wave technology is already used in unborn baby scans and by dentists for removing plaque.
