what spacing for the rebar?

I'm planning a driveway using 6' square slabs 6" thick over 6" packed gravel (this will not be a DIY project). The slabs will be 4" apart and interplanted with mondo grass (the slabs will actually be interconnected by two 6" wide "beams" evenly spaced on each side of the square. Is spacing the rebar on a 4" grid overkill?
