I can rodeo to the other side of an expressway and a couple freeways to hang a U-turn (with varying degrees of physical possibility or legal acceptability) in my region across the grass median but that doesn't necessarily mean that's a smart move that should be suggested to the average person with no regional experience. Likewise, I didn't know jaywalking wasn't a thing in terms of legal concepts in the UK until this thread and would be more prone to expect a more comfortable route to where other road users would explicitly expect me to take such an action. Point is, the data should be on the assumption of a complete greenhorn or someone who doesn't necessarily understand how getting around a particular locale works is using the map. > There is also the simple rendering issue, roads are already wide and > are very close or clipping buildings.
