A typical single lane road in the UK under national speed limits (60mph) have dashes that look like these - if not opposite (longer lines with shorter gaps)

Based on some other road details, like the barriers, bollards and road signs, I'd say it was modelled fairly realistically on UK roads.

Bingo - the dash spacing is still wrong, but it's based on the roads you might find around the Peak District (Cat and Fiddle, Snake Pass, etc.). I didn't reckon many people would mind the line spacing, but it'd be an easy fix

Wow, I was so wrong! TIL, and sorry I imposed an incorrect assumption.
