You are off by a factor of at least 5, because it's _passenger_ miles, not _vehicle_ miles. This is also why airlines are "so safe," because we put 300 people on them at a whack, if you were wondering where the "three orders of magnitude" actually comes from. It's still a man made machine being operated by humans. So it's 5.1. Three times safer than driving. You might apocryphally conclude they were at greater risk taking the astro van to the pad.
