Following the Lightlane concept, Streetsblog posts about “Contrail,” a frame-mounted chalking device that leaves a trail behind. Cool, but probably not so practical in the weather. Suggest a better idea is to create GPS contrails by equipping commuters during Bike to Work month with GPS units. Then auto-upload them to a municipal community, and share rides, like the CopenCycle concept.

Update
Treehugger picked up the topic and it’s from a 2008 Design 21 contest. The Power to the Pedal contest has a plethora bike blog topics, including Road Share: Bicycle Social Networking. The Bike Remora – attach your bike to a car for a while for a break – that looks like a curling stone and the awesome Sound from the Wind.

I remember seeing a snowboard wax once that would leave a slime green trail in the snow. I always figured it would just piss off other skiers. I kind of like the bike version idea though.
Practically, I don’t see it working, but for fun at an event, cool.
It looks cool on the street, but at the ATOC the yellow chalk on the road made choking clouds when all the cyclists rode over it. So, thanks, but no thanks if you are riding in front of me.
That’s correct—the yellow dust and they stopped doing that in later stages.
