For those of us standing on the side of the road waiting for a ride, what we lack is a means of connecting us to a driver who doesn't know we need them. But the technological solution to this problem is already close at hand - it is simply a matter of integrating three common functions:

* A mobile (cell) phone to inform the world of our current location and where we want to go.
* GPS units to work out where we are standing and which drivers are coming our way.
* A means of paying the driver a small fee for the ride.

1. Reminds me of the Hitchhiker's Guide to the Galaxy

In it, Ford Prefect produces an electronic "thumb" by which he is able to signal his need for a ride.
