The Bike Shield app never caught on because of spotty data in scenic areas. Also some cyclists don't like posting their GPS.
A transponder is the same thing as a bike light except it's at radio freque ncies, works around curves day or night, and motor vehicles tune in to the frequency posted on the "Share the Road; Get Cyclist Alerts At AM 1090" sig n.
It would require a dedicated receiver but it would be nice to give the moto rist a clue as to the distance to the cyclist around the curve, hidden behi nd trees, so 3 different frequencies at 3 different power levels could more or less indicate 3 different ranges, 40 - 50 m, 25-35m and 5-20 m.
The GA needs an idea of the cost on a production run basis.
Doubtful it would work; the signals especially in the vhf or uhf bands would still be subject to terrain scattering reflection etc.. Maybe low frequency electromagnetic induction? Assuming that wouldn't impose too much of a power loss on the bike's electrical system.
Then who is going to pay for it? Car manufacturers? Get the insurance industry behind it and you may have enough clout to get something like that installed, regulated, required, and paid for.

If you just wanted to go with one frequency for one range, say 30 m, then t he motorist could, if he wanted, tune into the AM channel posted on the Cal Trans sign just like getting traffic and other information.
Even with the 3 range system it could still be totally voluntary for both c yclists and motorists. The motorist could opt out of the dedicated receive r and not tune in to AM either.
Most motorists don't want to run over cyclists while many do want to look a t the scenery on California "historical highways" -- one mistake and you ar e history.
A car tried to pass a cyclist on a curve or hill in NoVa by veering into th e on coming lane. NoVa has even worse traffic than NorCal. The motorist h it an on coming vehicle.
2 - 3 billion cyclists on the planet and, with greater safety, even more ri ders.
Safety is a critical barrier to cycling for many. I will not cycle San Pas qual or Campo Rd.
Windshield wipers and bike lights were introduced before they were required .
This is one of those things that that could be started off with what libert arians like to call "voluntary" that is, ignore the fact that it ups the an te for safety. If most others have a new advantage and you don't keep up y ou lose ground.
Cyclists will know motorists will probably slack off and look at the ocean thinking they'll get an alert for every cyclist around the curve.
Probably a more expensive longer range system.
The FCC said no licenses would be required for such a short range system, s ame as those $6 RC helicopters they sell at Vons in the clearance rack alon g with Thai fermented anchovy sauce.

That was certainly the case when bike lights first appeared. In some ways it's even more true today when up to a third of riders still ride w/o light s _because_ it's now illegal.

VC 21201, Requirements for Bicycle Equipment
California sets certain minimum requirements for bicycles that operate on p ublic roadways. These include:
Each bike must have a brake that will allow a cyclist to stop one wheel on clean, dry, level pavement. A bike must have handlebars that rest below the user?s shoulder level. A user?s bicycle must be an appropriate size that allows the op erator to safely use it in an upright position, with the ability to put one foot on the ground. Any bicycle that operates on a highway or public roadway in the dark mu st have a lamp emitting white light, a red reflector on the rear of the bic ycle, and white or yellow reflectors on the pedals. A rider may attach a wh ite light illuminating lamp to himself or herself in lieu of the first requ irement.
~~~~~~~~~~~~~~~~~
The law needs to be updated for lights as well as transponders because a re ar red light is more valuable than the front white light. Any rider who is n't using any lights is either suicidal and/or doesn't want to be visible. I often keep extra $1 button cell lights and give them to any nearby guber s who don't have one. They can turn it on after a cop pulls them over.
The City of Tucson - Pima Cnty is very cycling friendly, providing free tra ining, free lunch and I believe free bike lights.

First no driver will tune in... but if I do, I get a beep beep beep on my radio? That tells me a biker is nearby but nothing else. A light or flashing light will be much better for the biker... and asks nothing of the driver.
Now if we could equip all the deer around here with transponders.....
You are right. We'd all have to be sharing GPS data or equipped with a system similar to aircraft collision avoidance radar systems, with a display or voice that tells you where the threat is.
To just know there was a bicycle in proximity to an automobile would be useless.
There's an exponential decline in the odds of collision as you move away from traffic outside of the white line. One meter of smooth pavement outside the rumble strip would save a lot of lives.
The problem is many road beds don't have that 1 meter.
Since CalTrans is willing to try _anything_ to keep NorCal roads open they ought to start passive tunnel building:
Anchor pre fabricated Quonset like tunnel segments to the hill side on sections prone to mud slides. Shove enough dirt down on top of the structure to distribute and soften the impact of any large rocks rolling down next mudslide.
The tunnel segments could then be wide enough to accommodate a bike lane. Trying to bulldoze the entire side of the mountain for an extra m of road bed may require a gazillion tons of fill, i.e., Hwy 299 2 years ago.
Less traffic doesn't necessarily extrapolate linearly to less accidents because everyone is off guard.
In the city everyone is always aware there are other cyclists, pedestrians as well as motorists nearby.
