Heard on FRS. What was it?

So, I was in the wrenching on the car in the garage with the scanner on in the background, when I hear something like: " ... red over black semi truck, turning right on 35th street, two Arabic women sitting on porch at 37th st, .... , UPS truck parked on side of road 40th street, ... ". He faded out, then came back again with similar transmissions describing what he saw, but now he was on a major cross street going west instead of north. Freq. was 462.6375Mhz. I could hear him just over 1/2 mile away and when he let up on the mic., it sounded like a typical FRS walke talkie with the silly roger beep.



The only thing that comes to mind as to what this might be would be the Google Maps car, but why would they be doing something like that?



Other ideas??
