Sorry but as a cyclist, the last thing I want is your "RF" version. While the display on the back of the forward large vehicle is a good idea, any thing that requires a motorist to take their eyes off the road in front of them is a bad idea. Transmitting an RF signal to the vehicle behind so that they can gaze at their monitor vice watching the road ahead is a bad idea.

Drivers are already isolated enough from the road environment... they don't need "view by wire" to complicate things even further. Between Cell phones, CD players, tinted windows, GPS, DVD, french fries, coffee, talking passengers and climate control, motorists only have their eyes to keep in touch with the motoring environment... don't distract them even further.
