The Velo AI smart bike light.

"In moving from radar to a camera-based solution, the aim was to create a device that could tell the cyclist 'a lot more about what's going on in the world and do a lot of things that the radar can't do'. The device would need to help cyclists by providing situational awareness and alerts about nearby vehicles. This includes the ability to distinguish, using computer vision algorithms, between different vehicle types, as well as to estimate their relative speed and to identify and predict driver behaviour."

"Raspberry Pi Compute Module 4 is in effect the brain of the Copilot, aided by a custom Hailo AI co-processor to run the neural networks required for the device's computer vision. A fixed-lens Arducam camera is used to record video footage."

"The Copilot is supplied with a mount to fix it to a bike's seat post or saddle rail, with the camera facing rearward. The AI analyses the live video footage and, depending on the type of driver behaviour detected, custom alerts may be triggered -- audible for the cyclist, and flashing LED light patterns to alert the driver behind."

The article doesn't mention it, but "velo" means bike in French.
