Maybe some type of telemetry tool to send information back to the support vehicle?

Used to track start/stop times and finish position.

Also intermediate times if the course is so equipped.

I suspect you're pretty much right. It may actually be something like a Surface Accoustic Wave Transponder or similar device, triggered to report its ID number when pinged by a transmitter when crossing a particular point. I believe a lot of big runs now put them on the hoardes of runners so they can time everyone's start and stop times by computers, which are rented from outfits that specialize in this service. I used to be involved in enduro motorcycle competition, and we were looking at similar technology.

Something like that would be particularly useful in bike racing, where the peloton comes rumbling across the finish line and everyone in it finishes in the same couple of seconds.

There's a big steel plate embedded in the top of the hill. How do you think he climbs so fast?

the teams are using them to provide power to heat their flasks of coffee. Actually, they are in the downtube (there is a small tap at the bottom) - the dynamo heats the whole tube.

Milk is held in the stem in the airstream to keep it cool.

I thought you meant the leader's jersey...definitely something with which I would not be familiar. ;-)
