So you never miss that great picture. you get 4 minutes to tell the cam to keep the last shots. if nothing happens it goes into wait mode.

Many cameras do this for video, and did at least as early as 2008. (The one I'm thinking of is the Casio Exilim Pro EX-F1.) Canon's "Wonder Camera" concept camera, shown in 2010, did this for photos, with a 20-minute buffer, IIRC.

Isn't this just a dashcam, or any security camera? And if it's a hand-held camera, the last 4 minutes are likely to show the inside of your pocket.

This must surely have been fully baked by the mid 90's with some webcam apps.

Yes, GoPro type cameras sort of do this

//constantly// can't really be true - there will be at the very least a frame-rate. And what about shutter speed, aperture, focus?

As [Max] indicated, most of the interesting stuff happens when you back is turned.
