In any case the problem has been solved with devices like this.

The problems are daunting to a novice. You really need a lot of training as an EE to figure this stuff out.
True, but it's always good to think as an outsider since people working on the problems from within the field tend to get their minds stuck in the same patterns and have trouble coming up with innovative ideas.
If multiple cars are broadcasting on the same frequency that is designated for a certain lane, they could each have a unique tone that would distinguish them. As different vehicles come into range, they could listen for what tones are present on the frequency and automatically select an unused tone. Idk how astute tone-recognition is but as I recall the horrible grinding sound that dial-up modems would make in the 90s connecting to AOL consisted of a lot of different tones being played simultaneously.
How many vehicles in each lane does each vehicle need to keep track of? If each one broadcasts its position and speed relative to others, couldn't onboard computers triangulate all the positions and distances of vehicles in their surroundings?
