I saw the above video where YouTube star Mark Rober tested the fastest seat on a coaster, but subsequently got kicked out of a park for having his cell phone out on a ride. As a big fan with a 7 year old son who loves him too it was honestly disappointing to see. The parks though have good reason to take this seriously though as there have been a number of major injuries caused by foreign objects on rides with lawsuits looking to hold the parks responsible.
