I can see his pointy little ears poking through the living room window by the time I roll up. Before I can see the house, before he even sleepily raises himself from his dog bed, my boy Kickflip knows I'm coming. And it's all thanks to the space-ship hum of my Chevy Blazer EV.

I'm sure you've heard it, or something similar, when a neighbor's hybrid or EV drives by. Since 2016, the feds have required all EVs and hybrids to emit a pedestrian warning noise when traveling below 30 km/h (18.6 mph), ensuring that your local vision-impaired jogger isn't surprised by a 5,000-pound car moving in complete silence. Above that speed, the tire roar of the car is loud enough to alert you on your own, the thinking goes.

Each brand uses a slightly different approach, with Tesla's warning sound being the most cartoonish and space-ship-like to my ears, and some sounding closer to the unsexy, platonic ideal warning sound: pink noise. Yet most stick to the same basic approach, adopting the soundtrack of an idling hoverboard or a vacuum cleaner from the year 3,000. Listen to a Hyundai or a Toyota or a Honda or a Chevy drive by on electric power alone, and you'd be hard-pressed to hear the difference.
