McLaren believe they may have discovered a practical way to eliminate the windscreen wiper – in use since 1903.
It is thought to involve using ultrasound to send 30kHz waves across the windshield, which would keep it clear of any debris, even those really horrible insect remains that can build up and obstruct your view.
How does it stop such debris? By creating a force field that stops rain, snow, or insects ever reaching the windshield. If they can’t touch it, then the glass will remain clean and clear.
