Since it appears sauropods were herd animals, some will be feeding and 
others won't. Herd animals keep informal lookout for predators and when
a predator is spotted they'll react in a number of ways, from stopping
feeding and keeping alert to moving away. A creature of that mass has a
lot of inertia at any speed.
