Drivers, on the other hand, will be alerted via a heads-up display on the windshield if a bicycle's nearby, which is especially useful if it's coming from a blind spot. It's an intriguing idea, but if it works is another matter, as not everyone drives a Volvo -- also, some people might not be too keen on uploading their locations to the cloud. Several automakers have shown off V2X (vehicle to environment) systems that connect locally and directly, but they aren't on the market yet. If you'd like to know more about the concept then stay tuned for more details, because we'll be seeing it in person at CES 2015.
