McLaren is replacing windshield wipers with ultrasonic force field from jets

I’m a car guy who loves working on his own car. And although I love do-it-yourself repairs, I hate changing windshield wipers.

No matter how many times I do it – and I do it often because I live in rainy Portland, Oregon – I struggle with it every time. One time, I even left the wiper-less wiper arm suspended at full extension and it slammed down, shattering my windshield.

You’d imagine my delight, then, when I learned this week that supercar and hypercar-maker, McLaren is working on replacing windshield wipers with an ultrasonic force field.

Sound too crazy to be real? Well, turns out, jetfighters already use a similar system to keep the cockpit domes clear of rain and bug guts.

Here’s how Digital Trends describes the technology: “An ultra-sonic transducer is attached to the windscreen that produces incredibly high frequency sound waves – not even audible to bats. These sound waves in turn create miniscule vibrations which shake water, dirt, bugs, and possibly parking tickets loose from the windscreen.”

Not only is this tech seriously cool, it also improves aerodynamics. Before the implementation of a force field, McLaren has been stuck with using an awkward-looking mono-wiper. Even though one creates less turbulence than two, it still creates more than none. Plus, throwing the wiper arm and wiper motor into the parts bin saves weight, albeit minimal. In the pursuit of power, though, every ounce counts.

So my hat is off to the Brits over at race-obsessed McLaren for solving the one problem most people didn’t know existed. Now I just need to figure out how to work this system onto my Toyota Land Cruiser … hmm.

Sylvester Stallone and Michael B. Jordan in Creed.

Good sports movies are fairly easy to come by, but great ones can be almost impossible to find. Over the years, the Rocky and Creed franchises have produced movies that fall into each of those categories. When they're good, the movies in this franchise are among the best fighting movies ever made. Even when they're only okay, though, they're still pretty great sports movies.

With the recent release of Creed III, it feels like the appropriate time to take stock of the entire franchise and determine which Rocky movies rise to the top and which ones sink to the bottom. A great Rocky or Creed movie can take a wide variety of  forms, but what matters most is the emotion it evokes in the viewer, and how authentic those feelings are.
