I understand this.  At highway speeds, that's a mile and 1/2 of travel, at 
least, which I think is gonna make it hard to use FRS power levels any way.

This is why Apple and Google use "speed averages", extracted from their mobile 
phone devices, to show traffic problems. It is a much lower bandwidth and easier 
to manage indicator of "traffic load".  A picture is only worth a thousand 
words, if you have it.  If you can say 1,000 words before you get the picture, 
then the picture is already dated information when you get it.
