I've always thought that gridlock is partly a product of all the micro-pauses between seeing the car in front of us move and reacting to that. A grid system might be able to eliminate these pauses and hence remove what seems to me, a major cause of congestion. A grid might also be able to help with other similar traffic bottlenecks, such as merging and changes in direction.
The only problem is, you'd have to give up some control of your car when in heavy traffic - but hey, you never had much anyway.
