This is one of the weirdest, coolest, and most creative technological innovations I’ve seen recently.
Two years ago, the New Mexico Department of Transportation decided to spice up a particularly desolate stretch of Route 66 between Albuquerque and Tijeras by adding grooves in the road that will play music when you drive over them. If you drive the speed limit of 45 mph for the quarter-mile stretch, you can hear “America the Beautiful” play through the vibrations in your car’s wheels.
The grooves in the road work just like the rumble strips or “drunk bumps” that vibrate your car when you start to drift out of your lane. But these rumble strips are precisely positioned to create different pitches when you drive over them. The result? The notes to “America the Beautiful” rising from the bottom of your car.
