Well it definitely depends on how far you are from the nearest tower. I am parked as close as I can be to it and I cannot get the signal to drop any way I try it.
I held my finger in "the sweet spot" as I drove away and after about 2 miles I started to loose bars. It didn't seem to happen as quickly or completely as when I was stationary testing it, but it did eventually drop to 1 bar. I never actually went to no service though.
So depending on topography I suppose you have a 1.5-2 mile radius from the tower to not be affected by this.
This was only one test however and cannot reasonably be called a result unless more tests are done and any variables are removed, but still compelling non the less.
People could start to blame AT&T for not having more towers
