Well I shore would hope so.  I bet it took them a quarter mile to get up
to 60 mph.  Looking at it the other way, they are saying that because
the bus decelerated from 60 to 0 in 160 feet, it will accelerate from
0 to 60 in 320 feet?  Get real!  Bad math on their part, methinks, in
that last sentence.  I think it should be more like the *square root* of
the distance, but I'm not sure.  My last physics class was many years ago.
