It really depends on vibration and movement. I think in that sense, daily drivers have it worse for flex pipes because they make the same repetitive motions over and over again, where as the track sees more extreme movement, but not in a repetitive way (and not every day either).

On one hand, Scott'll maybe have to replace the flex every few years, where as he could go through a number of non-flex pipes before he even finds one that works. I'd go with the flex in Scott's case as well, if it were my choice.
