FYI there is a typo in the home page:

*plans (presumably)

"So the final product is a multi-camera, rear-facing bike-light, which uses object detection and depth mapping to track the cars behind you - and know their x, y, and z position relative to you (and the x, y, and z of their edges, which is important).

What does it do with this information?

It's normally blinking/patterning like a normal bike light, and if it detects danger, it does one of two actions, and sometimes both:

1. Starts flashing an ultra-bright strobe - to try to get the driver's attention

2. Initiates haptic feedback - to let the person riding the bike that they're in danger

3. Honks a car horn. This is if all else fails, and only happens if you are in certain danger"

I had this problem. I killed WhatsApp from the recent apps menu, and then restarted it. The "WhatsApp Web" menu item was then available.
