Just for some historical perspective, years ago the Mayor of Providence used to come up occasionally on Providence Fire (154.3700 at the time) and Providence Police (460.1000 for dispatch channel 1 at the time) and would identify as "Executive Car 1." I believe sometimes it would be the mayor himself on the radio and sometimes it would be the mayor's chauffeur. It was interesting to catch these transmissions as the dispatcher would suddenly become "extra polite" over the air with a lot of "yes sir" and "no sir" and "we will take care of that immediately sir" in the communications with the Mayor's car!
