You know what will go perfectly with those futuristic rocket-powered, heartrate-monitoring bikes? This smart helmet that Volvo wants to create. It's a two-way system that works by uploading both cyclists' and drivers' locations to Volvo's cloud. While a connected car's in-dash system makes that possible, the helmet needs to be linked to a bike app like Strava to do so. Bicyclists can then be warned that there's a car coming their way or crossing their path by warning lights built into the helmet.
