I don't remember exactly how far apart the roadbed electronics had to be
but 
it actually _wasn't_ very expensive (at least compared to some of the 
competing schemes).  Retrofitting a highway with them was literally just
1) 
Drill a hole; 2) Put small cylinder in hole; and if you were feeling 
generous 3) plop a dollop of concrete or asphalt on top of it.  Move X 
number of yards/feet down the lane and repeat.
