Cognitive Radios can sense the radio environment and can dynamically reconfigure their parameters to best support the user needs. This "intelligence" has been made possible in part by recent advances in Software Defined Radios. An important motivation for using Cognitive Radios has been mobility. Mobile Cognitive Radios can dynamically adjust to new environments and mission needs. An example is the multibillion dollar JTRS (Joint Tactical Radio System) project. Recently, Cognitive Radios have been engaged in making efficient use of the scarce spectrum, for example, exploiting White Spectrum and opportunistically sharing allocated but underutilized spectrum (Dynamic Spectrum Sharing). The crowded spectrum is a critical problem in urban environment and effects the deployment of new Vehicular Applications. In this talk we briefly review the evolution of cognitive radios in commercial environments. We then propose the aggressive use of Cognitive Radio technologies to allow vehicles to open "radio trails" in the urban grid and advocate the development of a "cognitive spectrum service" for the Vehicular Cloud.
