A lot of bikes are not made of metal except for the handlebars and wheels,
and even then a some wheels are not made of metal either.

To be honest, the only viable solution is a ramp up to a $10/gallon gas tax
with all the $$ going to construct a viable mass transit system that
everyone will WANT to use all the time because it better and faster than any
alternative. The politicos and robber/barons at the top of socioeconomic
pecking order will then just get bigger SUVs as the fuel cost is not an
issue to them.

As for the RFID tag, that was a bait. Sorry. IR sensors are very reliable
and can "see" a human with no problem. Especially one building up a sweat on
a bike! The only issue with IR for humans is at temps between 94F and 100F
bodies are background noise. Bikes are easy to detect with metal detectors
short range. Long range is too imprecise.
Visible light image analysis for spatial proximity and relative motion is
the best choice for detection of pedestrians and cyclists (and other
road-crossing critters). It is, however, rather cpu intensive. I suspect
that some specialized modifications to 3D game applications could be used to
construct a virtual model for sensor warnings is a short route to
functionality on this.
