If your system needs vehicle to infrastructure, vehicle to vehicle, and/or vehicle to cyclist, it is only one failure away from not working.
Battery dead on cyclist transponder? Road kill.
Intersection transponder off due to blackout? T-bone.
Vehicle transponder does exist (old car) or faulty? Crashola.
Sure it makes it easier to implement, but the implementation is much more brittle.
It's actually the other way around in that it's less brittle.
It gets us to autonomous driving sooner because it does two very important things.
Adds significant redundancy, and allows for traffic efficiency gains that these systems offer. This doesn't abandon other forms of detection, but augments them.
The fact is that autonomous cars have to be safer than human drivers by a significant margin. So you need things like sensor fusion, and v2v communication to add layers of protection.
Having nation wide v2v system that has passive transponder for bikes/pedestrians gives me additional protection with not just autonomous cars, but cars being driven by humans. Where the HUD of a vehicle can show me in the display even before the vehicle crests the hill.
Oh, and you wouldn't have a battery in a cyclist transponder. You just stick it in a way it is powered off the rotation of the wheel. We're not talking about a whole lot of power.
