Abnormally appearing in front of a car too quickly for the driver to react (toss a small transponder into the lane anonymously) is a low priority problem.
I think that you're imagining an automatic slam the brakes, swerve, in response to seeing a beacon in the road. No, of course not. Even if you insisted on enforcing that, it wouldn't be that hard for the technology to know that it is anomalous.
The purpose in my mind, which I outlined in my first remarks, is to alert the driver that a bike is ahead in the lane, or in a bike lane beside the lane, or approaching on a side street even. Exactly like you want him alerted by your tail light, your hi-viz jersey, your lane position, except probably from a little further off and even when the bike isn't actually visible. Even a very discreet alert at his console would probably be effective.
It's not that hard technologically to use motion to detect whether a sensor is on a bike, a pedestrian or walking. Or thrown, or laying in the street. It's more of a program architecture detail than a real challenge, or show-stopper.

The question in the technology and what can actually be done, is time. There aren't a lot of seconds available to prevent a collision. Time for the car to compute that there is a transponder or beacon in the path, time to confirm whether the signal correlates to an object or not, time to determine if the best safety measure is to brake or to steer, time to prepare the vehicle for heavy braking or steering, and time for the brakes to scrub off speed or for the steering to deflect the car. Might want to add in time to assess road traction to adjust the estimated time when braking must begin. In case of a warning intended to motivate the driver to prevent a collision,
These timing requirements are usually long enough that the car's safety system effectiveness has to be limited in speed. The timing requirements translates to a distance requirement based at least on road speed, and there is an upper limit for each type of sensor. 5 GHz V2V transponders have pretty significant ranges, sometimes more than the 150 to 200 m of a 77 GHz radar. So the car company might have to state in the owner's manual that the car safety system cannot be effective above some speed. For peds and pedalcyclists that's probably ok in cities, but for suburban to rural areas with 50+ mph 2 lane roads (with expected additional speeding), the crazy pickup could probably still git us.
This is all set against processing speed, data bus throughput, and sensor update timing. With the coming of monstrously powerful multi-processors from the likes of Nvidia, the computing aspect might be nailed, or we can see that it will be. If it takes 10 samplings of a sensor hit on a pedestrian, the time for the sensor (a little intelligent system all by itself) to generate each new sampling certainly figures in here as well. This is where a beacon (or a transponder that also acts like a beacon) could help a lot. It should be able to determine its own position rather reliably (GPS and differential GPS) and simplify the task left to the in-car system.
Somehow cybersecurity must also be considered, at least man-in-the-middle attacks. If it is a braking or steering system, functional safety must also be followed to manage the potential for induced steering or braking errors.
So what's the point? WPHamilton mentioned "program architecture" in a previous post. I want to show some of the system architecture issues gleaned from my current experience in the collision mitigation/avoidance field and some more general topics in safety of electronic systems. I think the auto companies are coming around to understanding what this really takes, and that not to engineer the systems really carefully can actually have terrible consequences. Glossing over the downsides should now be a dead issue, at least with awareness of the Uber/Tesla problems, and with Volvo's proof that a solution exists.

Hopefully, this sort of device-X recognition will be in many (or most) vehicles in the future. So long as the device isn't ever tied to someone's identity (and I can't see why it would ever need to be), this sort of thing makes sense. Provide simple notifications and warnings, in the cockpit, and on "auto-driving" units provide avoidance/braking mechanisms to deal with it.
Of course, there are minor downsides with portable/wearable units like that, if/when vehicles become "automatic" ... Imagine someone lining up a dozen of these things across the roadway, as a prelude to a carjacking. Wouldn't be hard to do. Lay out a dozen of them, wait for the "automatic" car to come along, and zip zip it's done.

The automatic car should be equipped with a means to confirm if the line of beacons is a line of individuals. Of course in the design, the relative risks of error have to be evaluated.

The drawback is that RFID can only respond to a query with an announcement that it is present, (with its hardcoded ID), but cannot tell where it is. As opposed to ADS-B Out which can provide its exact GPS coordinates. Of course ADS-B would require a power source in order to constantly process its GPS location. I'm not sure telling the AV's onboard computer that "there is a cyclist somewhere" would be of any help.
I saw a demo at a show last fall (Pack Expo in Vegas), I believe the demo was with Turck (or maybe HARTING). I need to do more digging into the the application/demo. I don't have enough time right now to go any deeper, but my recollection was that these were none powered tags, it might have been two tags on each carrier and software computed the distance info. The demo was on a belt, making it less applicable to an open road application.
Designed for asset tracking applications in warehouses, manufacturing plants and other large indoor facilities, the new ATR7000 RTLS reader identifies and analyzes the coordinates of all passive RFID tags in its coverage area, providing real-time visibility into the pinpoint location of all tagged assets.

Gawd, I'd love to use a detection device on my bike, especially if it caused a motorist's vehicle to avoid a close pass or a hit from behind. Of course, my son in law hates driving my daughter's new car, with it's autocorrect steering.

I t woudl be interesting to see what a car did if another car, coming head-on, crossed the center line while the first car was passing a bike on the first car's right.

I see a lot of positives for this V2V technology.
Traffic lights would be aware that a cyclist is approaching so no more dealing with faulty inductive loops or poorly aligned camera detectors. In my city after this winter 90% of the intersections I approach no longer detect me as the camera is pointed in the wrong place, no detection, no green light ... ever.
To address the near universal habit of drivers blowing past the stop line at stop signs even visibility is poor, automatic braking systems could prevent you from flying over someone's hood or getting t-boned. Ditto for vehicles backing out of driveways and people opening doors into traffic.

Detector beacons should be optional and free for bicycles and pedestrians but mandatory for motor vehicles.

Using GPS data to talk to Google Maps
I was surprised to see so many people arguing against having a device that communicates to drivers there is a cyclist ahead. I saw some good points with regards to batteries and privacy but even then, I would personally love to have a way to let my fellow drivers that I am in the road with them. Any warning is better than nothing. This is the same reason I use a flashing light.
One idea I have been thinking for a while is using my GPS data (either Garmin or an app on my phone (Strava Beacon, etc)) to upload my location to the cloud. Currently, I use this to let my family members know where I am. I wouldn't mind if this same data is uploaded (anonymously) to a database of current cyclist on the road. It wouldn't record that Joe Doe is on the road, It would only record that a cyclist is on the road, at a certain speed.
From there, car makers can access this data and populate their maps. The reality is that there are a lot of drivers currently using Google Maps, Apple Maps, Android Car or AppleCarplay while they drive. The number of drivers and cars with this service will only increase in the future. These apps can communicate to the database and populate hazards on the road. An app called Waze (now owned by Google) uses driver source data to notify drivers that a police or hazard is X miles ahead - so the technology to update hazards on maps exist.
SUMMARY:
- Your GPS/cellphone communicates your location and speed - anonymously
- Map services/Cars access database and warn drivers know that there is a cyclist on the road: "Watch out, cyclist in the road in 1 mile"
Would you be against this kind of technology? what are your concerns?

So I would have preferred that the app would not only identify where the cops and the bicycles are but also randomly and falsely input many more locations where they are too. The good driver would take caution - as he should - to drive carefully everywhere but the bad driver - not trusting the app - may eventually get nabbed, as he should.
This is because drivers should drive carefully not because they don't want to get caught, but because driving carefully is the right thing to do.

Another crutch. Car drivers will assume all bikes have working transponders, and won't even bother looking for us anymore... at least some of those who may have otherwise been looking.

Frankly, the beacon thing is a losing tech for collision avoidance. A better option is on the road today:

my reaction can be summarized as "b.s."
long version, including the reactions of many others -- this is just another variation of the invented "jaywalking" laws that shifted the burden from driver responsibility and liability to regarding pedestrians and cyclists as disposable, expendable and collateral damage in the greater interest of ensuring motorists and motor vehicles aren't inconvenienced.

You should not have to "hardware up" to ride a ******g bicycle on the roads! I believe wholeheartedly that if driverless cars can't be programmed to not kill walkers or cyclists, that it is legitimate self defense for those of us who walk or pedal to do whatever is necessary to disable those cars whether they belong to us or not. No difference between that and kicking the crap out of the pitbull that goes after my little beagle.

Well, all of those human-driven cars are driven by different people. One programmer or team of programmers would be responsible for software design for all of those autonomous cars--fewer minds directing a larger number of cars. To me it's easy to make the distinction when viewed that way.

How do self-driving cars work? How close are we to large-scale deployment of them? And will we ever be able to trust AI with our lives?
