What’s with the UK motorway speed limit being 113? You’d have thought that they’d have picked a round number.

Hey did you know that Iberian rail gauge is what it is because Portugal used 5 Portuguese feet for their gauge and Spain 6 Castilian feet for their gauge and the are so damn close that splitting the difference wouldn’t have a detrimental affect on rolling stock for either. And so its officially 1668mm!
