In the LA Olympics I watched the road race and yah, it's just a zoom by. We were at least looking over a hill, so they climbed slowerly in front of us and then we could turn around and watch them zoom down the back of the hill. It was circuits too, so they went by a bunch of times.

For the TdF, my fantasy is to be on the route at a place with a TV to watch, and then run outside for the zoom past and then go back inside to watch the rest of the stage.
