Just to confirm - this affects only the *max* speed, correct? So if my defaults for single-track unclassified roads suggest 40mph, but tags say we're allowed to do up to 60mph (both quite reasonable here in Scotland, where the National Speed Limit is unattainable on many roads), then the map won't try to take me down the narrow roads just because the allowed maximum is higher? Or will I need to reformulate my speed rules to avoid increasing speed class? (And, if so, does such a reformulation need to be in the default rules?) P.S. Please would you post patches in a text/* MIME-type (ideally text/x-patch)? application/x-download isn't really appropriate for diffs, as it doesn't imply any charset or line-end conversions, and is harder to display inline.
