Corporate myths (Score 1)

Hey guys, I've loved your show since the first season. Keep going. Were there myths which you seriously considered busting on the show, but were nixed not due to safety issues, but rather, to liability concerns or fear of being sued by outside parties which might disagree with your methods and/or conclusions? For example, if there really were a way to reliably beat police radar, (or any other such myth) would you ever put it on the show? Have you ever tried to replicate the results of a standards body (e.g. ANSI - steel toed boots) but actually come up with a different conclusion? Has there been a myth where you seriously took an existing test standard to task and thus caused it to change?
