Whether you’ve got a nasty case of triskaidekaphobia, an unbridled passion for slasher movies or you’re just a little superstitious, seeing Friday the 13th pop up on your calendar can elicit a sense of dread and gloom. October is the second month of 2017 to see the 13th day fall on a Friday; the first having already passed us in January. But, the question is this – is there any truth to the bad-luck association? The Dutch Centre for Insurance Statistics would say no, given a study it released in 2008 that found the average rate of traffic accidents in the Netherlands actually fell on Friday the 13th, presumably because people drove more carefully or simply chose not to drive at all. Regardless, it got us thinking – what car stuff out there is considered unlucky?
