Not the same. It could complement but not replace a general purpose system.
Scania has a self driving truck convoy where a manned truck is followed by several driver less trucks using such beacons. It is not a trivial solution once you dig into it- normal wifi is too slow at highway speeds, and once the air is congested and re-transmissions occur it is even slower. Scania is using 802.11p [1] and still has backups for when connection is lost or delayed.
