Ricochet isn't great in a moving vehicle, but its not completely broken. In
my experience, it can usually "catch up" when you get to a traffic light.

In any case, I already have a Ricochet, so I figured I'd play around with it.
If I do find some critical wireless app for the empeg, I'll invest in a better
solution (although the CDPD/GPS combo sounds like a winner).
