I agree with this. 2.4 can only carry so much signal. Plus, if I am going to have to look at a small (7 inch) screen on my dash, then I would like it to be as clear as possible. That means not only the signal has to be clean, but the camera itself has to be hi-res. The more pixels the better, and the better lens on the camera, the better.
Fisheye lenses, like you see on GoPros, are OK, but they do distort the picture somewhat.
