To use a driveshaft transmission instead of direct drive you cause yourself at least 3 headaches that direct drive saves you.
First: with the addition of driveshafts, and gearboxes/diffs you create a nasty weight issue which you wouldn't have otherwise, and with the added weight you give yourself more work when you calculate C.O.G.
Second: cost. More kit, more exspense through design/development/manufacture/shipping etc.
Third: reliabality and maintainance costs. With the addition of gearboxes and driveshafts you have more to worry about going wrong!
Another good reason, as mentioned by an earlier post, is power consumption. Direct drive is far more efficient transfer of power.
