Displaying one of the attached USB cameras on the LCD display will be needed for reversing or for example for monitoring purposes while driving.

omxplayer seems to be a good solution.

Example

omxplayer -o local /opt/retropie/supplementary/splashscreen/retropie-2015-carbon-video-4x3.mp4

In case of latency problems with the actual camera try following options:

options " --live --threshold 0 --video_queue=1" and latency is minimal i think no issue for back/reverse camera.

Pi camera module HDMI extension module. This makes it possible to use a long HDMI cable to run from the back of the car to the front.

Got webcam live view working using but with very poor quality. Keep in mind that this is a very old webcam that I'm using currently.

omxplayer -o local /dev/video0

Responsiveness using following options seems to be pretty good

omxplayer -o local --live --threshold 0 --video_queue=1 /dev/video0

Convert analog existing camera to USB camera using current wiring to tulp connector (example) and using that as input for something like this EasyCap device.
