Because this would lead to lots of injury, and a coaster would have to reach speeds up to 200-mph, and have the wheels, and bolts in order to make the full loop. This is Technology that we do not yet have for ride design
clothoid/ klothoid
Clothoid Loop A vertical loop that is teardrop shaped Roller coasters today employ clothoid loops rather than the circular loops of earlier roller coasters. This is because circular loops require greater entry speeds to complete the loop. The greater entry speeds subject passengers to greater centripetal acceleration through the lower half of the loop, therefore greater G's. If the radius is reduced at the top of the loop, the centripetal acceleration is increased sufficiently to keep the passengers and the train from slowing too much as they move through the loop. A large radius is kept through the bottom half of the loop, thereby reducing the centripetal acceleration and the G's acting on the passengers.
The noun 'roller coaster' has no standard collective noun since most roller coasters are not in a group. However, a collective noun is an informal part of language. Any noun the fits the situation can function as a collective noun; for example, a scream of roller coasters, a maze of roller coasters, a park of roller coasters, a tour of roller coasters, etc.
