Testing Roller Coasters WIth Fred

An anonymous reader submits: "An AP article looks at the science of roller coaster testing. In general, a coaster must pass a "Fred" test, Fred being something analgous to a crash test dummy used in the automobile industry. Fred has a bunch of sensors in him that record data during the ride's operation and provide it all to engineers ensuring a ride's safety. Also discussed is pending regulation over G-Forces in New Joisey."
