Some of the limits here are ridiculously low (70-80 km/h on certain highways - seriously?). Yet some of them are ridiculously high. For example, on Tregunter Path, pedestrians (sometimes bikes) and cars regularly mix on a section of pure road where there is no pavement, but the speed limit remains the default 50km/h (30mph, and contrast the UK 20mph in built-up areas). Of course, there is never any speeding enforcement carried out on that road. It's ridiculous. But I suppose if no-one complains, then the squeaky wheel doesn't get the grease.
