This is the answer. Another good solution is the
Bike Eye mirror that mounts to your frame. Fairly discrete and a way better mirror than most.

I don't think that a camera would be a better solution than a mirror even if the camera was free.
at night, the mirror works even better. Car lights make it much easier to identify an approaching car.
The thing I find with mirrors and that I think would be an even bigger problem with a camera/lcd approach is the distance vision. Riding on rural roads or highways, you need to know when a car is approaching way back. A fairly long distance away, you can easily hear the tire noise on the pavement. With a mirror either on your bike or body, you can adjust your body position to get a wider view. If the mirror is not one of those damned convex mirrors, you'll have a very good ability to see what's out in the distance. An LCD is not going to do that well and is going to be better with a wider angle view.
There was a (Danish?) company that was making a device that was a combination tail light and proximity detector. As a car approached, the tail light got more noticeable and the bar mount display indicated relative position. I believe Garmin bought them and I expect we'll see that pop up in their bike computer line in a year or two.
