There are a number of commercial solutions in this space. It's weird when there's a press release like this that acts like their solution is completely novel and unrelated to anything else.
Roadio has front and rear facing cameras with AI driven object detection to help keep cyclists and motor scooter riders safer.
Garmin (amongst others) has had a rear mounted radar (and bike light) system for a while. They also have one with a camera built in.
Roadio is primarily a camera and costs around $265 USD. The Garmin is also a camera and also costs over $300 USD. Neither reports to a central service to map the results for other users.
