(Assuming I'm understanding you correctly,) if the issue were only other vehicles, this might be feasible. However, the world includes much more than just the other vehicles on the road, and the road and its environs aren't static.
I can imagine something similar to what you're proposing being a part of the overall system, I suspect there will always be the need for something vehicle-based that "sees" the environment.

Yeah I meant in addition to, not instead of.
And I was saying that these beacons should be just a part of the car and super cheap. The beacon just says "hey I'm a Prius and this is my speed direction and location"
But you'd have to make them completely anon - we already have too much activity tracking.
So the devices should cycle through random IDs that just spray out the specs of the vehicle, but they change frequently the ID so you can just say that a smart car would know that it just sees various cars - not that it knows that "Jim is just ahead on the left"

Imagine you are potentially the first autonomous car maker to market. You need to build a car that assumes no other cars can talk to it. The idea you have is good, but is probably a solution that gets addressed much farther down the road.
Wouldnt any of these smart cars be able to know they physical volumes of many number of cars, including themselves, as well as communicate with eachother - and share their velocity, direction, volume, intentions so as to have a hive mind of the moving bodies?
What if you also just had a beacon which reported this information to other cars in a short network where the driver is human - so the smart cars all know where the human driver operated cars are.
Then, in addition, you collect all the point data, from lidar, you subtract the known data points given "a prius with a shape and mass and volume of this moving at a speed of that - and over time you have built out a complete point cloud of the static, non-variable topology?
rather than spending $75,000 on one lidar periscope, spend 75,000 on developing a beacon such that all cars are telling eachother where they are, their mass/volume and speed?
