FNTP/WSMP replace the IP layer with a different albeit null) networking

bytes of protocol "overhead") designed to be small and efficient and
tailored to the simple single-hop broadcast over capacity constrained RF
channels.
So that possibly makes sense internally to the car, although possibly not. It
doesn't make a lot of sense to me between cars, except perhaps in the most
restricted applications. When you talk about capacity constrained RF
channels, it sounds like you're talking about car-to-car traffic, or
car-to-infrastructure traffic. But this constrained port mapping protocol
sounds way too restrictive for either of those contexts.
neither 802.11p or generic wifi are particularly capacity constrained.
